Fallensword
A little game I play, FallenSword, is a browser based MMORPG type game. I quite like it as one can level up and choose what skills to focus in, buy new armour, weapons, etc at the auction house (which is completely player driven). In addition you can buy FallenSword points, either with ingame money, or with real money if you want to level up faster (I prefer not to do that, as im a skinflint).
If you wish to try it out, and I recommend you do, have a looksee here. It is completely free to play, so give it a whirl!
PS: I no longer play such a game, but if someone gets in touch with me via this blog and knows my real name, nick, where i hang out (AND if my account is still alive!), I may gift you some FSPs. Yeah its a bitch all those conditions, but considering im giving them away for free (FSPS = rl money), I’d not bitch. 
PINKGOBLIN WANTS FSP’s!!!!!!!!!!!!!
haha, sorry but that offer is long closed now mr goblin
