I always run into great video game sites, and it's a pain to keep track of them all, even with bookmarks. That's why I'm starting this thread, y'allz. Let's share! (By the way, the "unheard-of" part is just to keep people from posting Gamespot or something.)
I'm really big on screenshots. CLEAR ones. And I like well-made tribute sites to niche games or retro games. Good, clean web design also gets me.
Hardcore Gaming 101 - Definitely one of my favorite game sites. Updated somewhat frequently with huge, comprehensive articles. Lots of screenshots, too.
The Chaos Regime (aka Gods Country) - I love the Bitmap Brothers! Preeminent pixel artists, classic games... Chaos Engine, Speedball, Gods, etc. And bonus points for having their game covers painted by Simon Bisley. This site is beautifully designed. You have to see their Gods fansite to believe it. WOW.
A Personal History of Computer Games - By Justin Hall, aka that dude that video taped himself crying. Now studies games at USC and seems much happier overall (good for him!). A really fun page about the computer games he liked.
Alone in the Past - French site. Can't read. Enjoy the screenshots and the games.
Postback - Another site I can't read (Spanish), but I enjoy the big, beefy screenshots.
Apple IIGS Gaming Fairway - Cute site about Apple II games.
There are more, but I can't remember / find them right now! Share your own!
