Lots of F2P (free2Play) games available. I really enjoyed Runes of Magic. It's really the only F2P (has an item mall) game I actually enjoyed.
It depends on what style of game you enjoy.
I am a rabid mmorpg fan and that's what Runes of Magic is. Graphics are pretty good and there is tons to do.
BTW: Don't play on an PvP servers. My main was on a pvp server and there just really wasn't that much activity, only ganking.
Also you might want to look into DDO (Dungeon&Dragons Online), though the graphics really are outdated and turned me off.
LOTRO is another pretty good f2p w/ item mall.
Hope those suggestions help. Sucks being cooped up and off your feet for days.
Take care and get well...
Regards,
