Alright, first up, this is a bit of a greedy thread. I want advice because I'm working design for listing my games:
http://wegetsignal.ca/games.htmlBUT, because I'm not a selfish butt and I
like love design references, I'd like to point out some sites that layout games really nicely as well.
http://mattmakesgames.com/ - You get a quick visual of each game and only by mouseover and then click do you get an involved, detailed view. I feel like you need a fair number of games to pull this one off, and of course Matt has a ton. Also good: the space and flow in the design lead your eyes immediately to the prize, the games! This is one of my favourites.
http://infiniteammo.ca/games/ - Gives a ton of focus to the top game, and has a lot of flexibility in the content. There are videos, screenshots, thumbnails for lightbox viewing. I like this primarily because it's aesthetically pleasing, but I feel like Aquaria is buried when it should be closer to the top (being the most popular game.) Then again, digging for Aquaria might cause people to discover the other games they hadn't tried; or perhaps people looking at games on an indie developer sites know exactly what they're looking for.
http://cactusquid.com/games.htm - All that I really want to point out about this style is that it gives you easy access to Genre and Rating. I also like that Cactus will rate his own games poorly which is pretty fun.
http://thatgamecompany.com/games/ - Again mostly an aesthetic choice, the entire site is pretty much oozing style anyway.
A lot of indies don't list their games. They have a blog and they talk mostly about the most recent game they're making. I feel like that's a bit of a mistake. What do you think?
A lot of companies also use their games page solely for their one big hit. This is probably not a terrible idea.
Some companies use their games page to give you a company history -
http://thebehemoth.com/games.html - this is interesting to me, and sort of reinforces what I mused up above. Those people interested enough to browse to your site probably know a bit about you and are interested in more meat and potatoes of who you are and why you do what you do.
Thoughts, comments, design inspirations/references, you name it.. let's do it.
