Free Webinar – DNA of a Blockbuster

DNA of a BlockbusterNot all game concepts are made equal. Depending on how they appeal to your audience, their success potential widely varies. Through my time managing creative teams at Ubisoft, I gradually realized how certain game concepts would have more market relevance and gained insights on what blockbusters were made of. I was able to identify how a franchise like Call of Duty tripled its sales with Modern Warfare and became a household of our industry. Later on, I was able to apply this approach as Creative Director on Rainbow 6 Patriots and identified a fantasy that would position this franchise reboot right into our collective concerns.

Tips on game balancing

Game balancing is key for game design. Finding the exact damage value for a weapon or the correct height for the jump of a character is exciting for game designers because it’s about the only moment where we can immediately see the impact of our decisions.

This feedback loop is so rewarding it can trick us into endless tweaking, tinkering and fiddling of spreadsheets. Focusing so much on details can often make us forget the big picture, and I want to give you my tips on how to approach game balancing.

Before going into more details, here is my short video on the subject.

Game balancing is creating dynamics

The most important notion is that elements of a game are meaningless on their own, as the player will never encounter them in a vacuum. An ability will always be confronted by obstacles. For gameplay to feel good, player tools must seem adapted to the challenge they help overcome. Game balancing - Mario jumpsThis lets players develop a consistent understanding of the game and leads to “aha moments” as they recognize patterns in the obstacles and know what ability to use.

The first level of Super Mario Bros proposes obstacles exactly matched to Mario’s jump, in height and length. This teaches the player the parameters of the key ability, and will allow to clearly evaluate options in navigating each level.

Games are systems of elements in interaction, and a dynamic always emerges from the ensemble. Because you want to give players a seamless experience interacting with your game dynamic, you should decide upon it first, then use this target to evaluate your balancing effort. It is the role of design to determine these interactions, and of game balancing to set parameters so things unfold as desired.

Another way to make a tool particularly adapted to a situation is to make it way more efficient compared to the others. Think of the classic RTS unit type cycle infantry/archer/cavalry, or even rock/paper/scissors. Once again, it is the clarity or the relationship that creates a satisfactory decision for players because it lets them learn more easily.

This illustrates the notion that game balancing is generally not about making the different elements equal, but rather creating strong discrepancies leading to clear dynamics and relationships.

Game theory applied to game balancing

Game Balancing - Nerfing dominant strategies

Hearthstone cards get nerfed if used in most decks.

With many moving parts, it is possible that strategies becomes way stronger than expected, to the point of making all other options useless, what game theory calls dominant strategies. If your gameplay relies on selecting the best approach, this will definitely hurt the depth of the decision process as well as gameplay variety.

In this case, you want to reduce the effectiveness of the elements that give so much strength to this strategy (also called nerfing) and make multiple options viable again. This will bring value back in the decision process by proposing a dilemma where all options are clear, the right one being uncertain (cf. Fun and uncertainty).

Very frequently, unforeseen strategies will divert from intended gameplay. On a shipped game, this will be called an exploit, but it can be addressed to some extend during development. If the testing team is given a list of the desired winning strategies for each situation, it will be able to validate that the intention is maintained, and verify that other options don’t unduly dominate.

Skill is very important when trying to basically break intended gameplay, this is why our balance testers at Relic were competitive level players. This type of workflow, makes the team able to evaluate the strength of the gameplay structure, find loopholes, and decide to react accordingly, or to leave these options available.

Conclusion

During the development of Street Fighter II, the team incorporated leniency to make special moves easier to execute, but a side effect made it possible to create unplanned combos. They viewed this as an interesting features and decided to keep it, which opened up some pretty dominating strategies. From there, it got refined and became the key mechanic of the whole fighting genre. This shows that we shouldn’t discard the value of emergence.

The team got pretty lucky to create such a successful gameplay through what was almost an oversight. This is why I think that an intentional approach is superior to better control the resulting game dynamic. Defining a clear target for gameplay then feeds into the game balancing process. It allows to evaluate the different strategies that emerge, and make informed and rational decisions before rushing to our beloved spreadsheets.

Interactivity as a Medium

Which of narrative or gameplay should take the lead in video games? It’s very common topic that polarizes both game devs and players. I was asked my opinion on the question through youtube, so here is my opinion on the balance between interactivity and gameplay.

Zero-Sum Games for Game Design

Zero-Sum games is a very important concept for game systems as well as rewards, so here is my perspective on it, as well as examples on what it means for game design.

If you want more details on how to balance games, I would point you to this article on Positive feedback by Ernest Adams, and if you are interested in Game Theory, head to my article on the topic.

Also, as we reached the 600 subscriber mark for our youtube channel, I want to thank you by letting you choose the topic of my next videos! Please write a question you want me to treat next in the comment section.

Warcraft 3 Randomness

Compared to Starcraft’s very predictible systems, Warcraft 3 and its randomness always puzzled me. Here are my conclusions on how such a random game can still be fit for competitive play.

Assassin’s Creed Combat system

While working at Ubisoft Montreal, I was involved with Assassin’s Creed, and we faced a situation where we realized that the combat system was largely perfectible, but we were specifically asked to stick with a design that we felt was rather poor. It took me several years to realize that it was the best decision, and I explain in this video how sometimes bad design is best.

Shooting isn’t the key mechanic of Quake

After last week video where I analyzed the way Halo shapes the combat dynamic for the average players, here is a quick look at Quake’s top competitive end.

Halo Multiplayer Combat

As a follow-up to last week’s video on the lessons from Pac-Man design, here is how they can apply to AAA games, with a short study of Halo’s multiplayer combat.

Lessons from Pac Man

I studied the game systems of Pac Man as I was working on a documentation process for the designers at Ubisoft Montreal. I wanted to use a simple game to showcase that process, but as I dug in the different resources available, I realized how refined this game’s systems were. This led to understanding game design principles that still stick with me today.

In the video, for the sake of brevity (also because I don’t fully understand the game’s systems), I used rather gross approximations, and I wanted to link you to a great article that properly covers the ghost AI of Pac-Man. Here it is: Understanding Pac-Man Ghost Behaviour by Chad Birch.
