i posted a list on my blog, and i continue to update it. any games that require you to pay after you reach a certain level, or which you need to buy "points" get dropped form my list. mostly looking for flash-based, free, low-commitment games.

abbreviated contents pasted here for convenience:
World of Pain 3 - Anime-style combat. Concentrate on one stat or style of fighting... and you'll beat the game in a day. It's nice to have a game with the right balance of puzzle, fight, and a clean win just before you get bored of it. (Online/Flash)
Arcuz - Run around, gain exp and level up. Be careful how you use your gems, they don't come easy and you'll kick yourself if you mess them up. Don't try to save-reload a mistake... it doesn't work. I stopped playing after I lost my sword doing that. (Online/Flash)
Shadowreign - Top down, semi-real-time combat style... like diablo, nice tutorial. Really fun to play for a free flash game. The skill tree is fun to explore. Also has a winnable conclusion. (Online/Flash)
