Like 10-12 years ago, when the 360/PS3 released.. There's tons of shitty indie games with local co-op, cuz the devs can't afford to implement online, but with modern mainstream games they're hard to come by.
I mean, if you want couch co-op games it's not that hard to find some, you just can't be picky and either have to go for older games or indie games most of the time.
and then toward the end of ps3/360 cycle, developers couldn't have steady framerate/fancy graphic with local split screen built-in so they dumped local co-op & splitscreen feature completely.
Me and my friends used to visit Co-Optimus site all the time to search for the latest co-op games to play on console. It was a glorious time!
Halo, Gears, Resistance (ps3), Resident Evil 5 (ps3 with their glow stick and gun accessories), Ghost Recons, 50 cents,Terminator Salvation, Mercenaries, etc. were the few gems that we played. Believe it or not, co-op feature made cheesy games less shitty and more entertaining
