Finished! Got to say, this was a fun bit of navel-gazing.
Really, the hardest thing was separating "stuff I like" from "stuff that I find myself drawing on." For example, I really dig Metroid Prime, but it hardly informs my own work- I don't make first person adventure games, at least not so far.
Edit: I've been asked a couple questions about this, so I thought I'd elaborate some here. The material on the left side of the image is what I draw on (so far as I can tell) when coming up with fictional ideas and concepts- a random character, the background for a world, the fluff premise for a game. The material on the right side is the stuff that's influenced & advanced how I think about game mechanics of all sorts. Pretty much everything on here comes highly recommended, feel free to ask if you want more details on something.
