Everquest 2, You could play with whoever you wished and fight whoever youwish. Lineage 2 FFA no factions besides player guilds, Eve? Same as Lineage. There's probably more MMORPG's that don't have this problem ^^
It's getting to that point for me, but I find games with limited races to get dull fast. Hopefully they will add more alien type races along with more stories for them.
Tired of the different colored humans.
Your case lacks ventilation. Any software that'll push your computer will generate heat. Get better case or more ventilation, it's not the game's fault.
