Ya, I played a majority of Halo 2-3 in split screen, it wasn't a bad experience by any means. The maps in Halo 4 that are sized like complex or larger, and enemy drops in Spartan OPS, just choke the system on split screen. Gold accounts aren't the problem here.
There's always been the issue of quality degradation / screen size with split screen. I'm talking Frame Rates. See I can do plenty bad without these issues but when I play split screen and I win like 1-10 games I gotta point the finger at choppy graphics. I am solidly 1/1 with wins and loss's on any game. Ok so I go split screen. I could expect to go to 1/2, win/loss. 1/10 I gotta say its not me, its the game. I never did this bad on Halo 2-3 in split screen. It's not like I can do worse with the jet boost they add'd.
