Game development








Hello! I'm Tom. I designed a game called Gunpoint, about rewiring things and punching people, and now I'm working on a new one called Heat Signature, about sneaking aboard randomly generated spaceships. Here's some more info on all the games I've worked on, here's the podcast I do, here are the videos I make on YouTube, here are some of the articles I wrote for PC Gamer, and here are two short stories I wrote for the Machine of Death collections.

    What To Do If Your Prototype Isn’t Fun

    I got an e-mail today from a developer who’s having trouble making any of their prototypes fun. I’m posting my reply here in case it’s of help to anyone else. This developer was writing because they liked Gunpoint, so that’s why all my examples are from that.

    I would suggest three things to bear in mind:

    1. Don’t judge one prototype mechanic against a whole finished game

    I don’t know if you’ve played the early prototypes in the DLC, but the first versions of Gunpoint didn’t have much going for them. I had you trying to jump on guards who turned around at random intervals, killing you instantly. By itself the jump wasn’t particularly interesting, but once I’d got it useable that’s when I added stuff like pouncing on guards and punching them, climbing on walls and mantling round corners. I didn’t know if any of these things would be particularly good, but as it turned out the punching bit was an unexpected highlight. It still wasn’t what you’d call ‘a fun game’, though, it needed years of thought and design and testing and redesign to make it all hang together.

    For a long time the Crosslink was just a theoretically interesting idea, most testers just said it had ‘potential’. It was pretty empty by itself, and it took a long time and lots of trial and error to design levels that managed to present interesting obstacles to your rewiring ability, without forcing you down a single path.

    2. Fun doesn’t come from game logic / mechanics alone

    The first thing that really felt ‘fun’ about Gunpoint was that endlessly punching guards thing, which isn’t mechanically interesting at all. There was no advantage to doing it, I just didn’t see a reason to prevent you. I found a sound effect of a belt being whipped, and drew an incredibly crude 2 frame animation, and something about the suddenness of that with the weirdly slap-like noise was funny, and being able to do it as rapidly as you could click was satisfying, and it worked. But the punching is not a good idea, it has no interesting implications or consequences, I just got lucky with the sound effect and some placeholder animation. So don’t expect an idea to feel fun right away if it doesn’t have those trappings yet.

    3. Figure out some smaller, specific, achievable goals

    ‘Fun’ is a big nebulous thing with many components, and it’s hard to approach without breaking it down. You’ll have to figure out for yourself what specific types of things you find fun, but as an example my checklist is something like this:

    Single, inherently satisfying actions: eg. throwing yourself through a plate glass window, or punching a guard in the face. These don’t have to be smart or interesting, and they usually only get fun once they have sound and maybe some basic animation or tweaking of their presentation. It’s quite easy to stumble on these through random experimentation.

    Some kind of special player ability: pretty much every game idea I get excited about starts with the words “You can…” For me it usually ends up being something you can’t do in real life, but it doesn’t have to be too far fetched: I love Hitman, and that game’s most outlandish ability is “You can dress up as other people”.

    Problems with many solutions: whatever it is you can do, I want a) some problem that can be solved with it, b) more than one way to do so, and c) interesting differences between the solutions. C is the tricky part.

    If you can figure out what your components of fun are, just pick one and see if you can achieve it. Don’t worry if the other stuff doesn’t arrive fully formed around it, each part might need its own journey through experimentation, testing, revision.

    Hope that helps!

    Ebreakey: Great article, I personally believe also that another thing that makes up fun in a game is what some people call "game feel" but it's really just making everything fun, for instance making your menus fun to interact with, your visuals and effects interesting and effective etc

    You also have to consider why people play your game and what they hope to get out of it, lots of people for example like to feel powerful and badass while others just want to be immersed in a world.

    There is a great video on "game feel" by grapefrukt I definetely recommend.

    Thanks, -eb

    YetiSeekingYeti: I've had this problem so many times, seeing it written about feels great.

    I've never tried to think of fun as a combination of smaller goals. I've always had it in my head as something atomic since it feels like such a basic, raw feeling. I've worked a lot with my plan being, "As soon as I can make it fun I'll worry about the rest". Which is probably why I've been disappointed with so many prototypes, despite meeting some of the criteria for a fun mechanic.

    I think reading this will be really helpful, thank you!

    HeadBobShartBlast: Good point from eBreaky, one of the best examples is yoshi's island on the SNES. From the opening credits to the graphics and especially the game play. It's designed with such integrity. It is feels how it looks, and there are layers and layers of clever. You must play it immediately.
