Yeah, i was just looking for something that me and my friends could play that had a high replay value, like zombie survival. Co-op campaigns aren't very fun to play over and over. I'll check out fear 3.
uh ghost recon 2 has the biggest replay value of any game ever. it was like BUILT around splitscreen. first off, each player can customize thier own character to look how they want with like 20 different separate outfit pieces each. then you have like 30+ maps to choose from, all very large and extremely indepth. then there are the gamemodes, you can do player vs player, you can do player vs player on huge maps with lots of bots, you can do 4 players vs a bunch of bots, there are objective gamemodes, which is basically where you have to complete certain objectives as a team while eliminating anyone trying to stop you, there are endless options. you can even do helicopter hunter, where you have to kill a certain amount of helicopters (which is extremely hard seeing as this is a psuedo-realistic game) before you die. there are also like 120+ weapons like a smoke grenade launcher, multiple heavy machine guns, snipers, assault rifles, you name it.
tl;dr AI is amazing, replay value to the max buy it if you havent already
