In which order do i finish these games? I hav lots of games i never finishd

[disolitude]

I'd play Halo ODST - its a short and very fun campaign

And I'd stop playing Dead space. You played for 5 hours. You've seen everything the game has to offer. If you beat that spinning tentacle mid game boss, thats the last cool thing in the game. May as well sell it after that...
