here are some more call of duty 4/5 and warhammer aka fpsmmo resident evil 5 and left4dead spore and starcraft II spellforce 2 and DoTA(warcraft3-battle.net)
I think COD5 and L4D cause it would just be a game were you are a soldier and you have 3 other people with you that are marines, you are the only ones living and you have to try to get out of the city. Or basically just a whole game about nazi zombies
monster hunter 2 freedom and monster hunter 2ndG, these game are popular in japan and people say its bad in america becuase its just a game that has no story line but theres more like improving weapons armor getting to see more exitement and cool monster, you can play online up to 4 players in psp
