To date, I've been playing a lot of Warcraft.
Prior to warcraft I played classic EQ through the Planes of Power expansion.

Unfortunately, the lastest patch looks like it will require a reinstall.
The last patch required a reinstall.
Not worth continuing to play warcraft if its going to require a reinstall for every patch.

Heroics and Battlegrounds are probably the most fun, arena style pvp is mostly bleh.
10-man raids are a lot more fun then 25-man's.
I software box, via Keyclone... so preferably something where this is an option.
Any suggestions on another game?
