Tactics Arena

Tactics Arena is a really fun turn-based strategy game. You play online in-browser (uses flash). It’s somewhat like chess, but the pieces have varying healths, different attack styles (involving magic, swords, archery, etc.). It’s a lot more fun than chess in my opinion. You can chat with your opponent if you wish. The game is free, but you can pay $5/month for premium service where you can get more characters (and protection from the free-account-wipes they do every couple of months). Try it out. You’ll be addicted shortly.
