See you keep making it sound like split screen drastically reduces the quality of a game, but that's just not accurate. And if it was, you wouldn't be here, because halo would be behind the curve. You see, good game design is not strictly about how much power engineers can give the engine, how many objects can be displayed at once, or how many options you can give the ai to use. In fact, it is entirely possible for these sorts of things to damage the design of a game, by getting the designers to focus on using their new toys, rather than being effective. In fact, a lot of good design involves accepting the fact that you have limited resources, and spending your time "cheating" those resources into a simple but clever facade to keep people entertained. So when I say I don't care if some of these superficial "advantages" are sacrificed for split screen, it is because I understand that these things are not what makes a game good. Whereas slightly more powerful engines can be nice to have, the impact having other people in real time interact in the game with you, has a greater effect on the game by an order of magnitude, as any form of a computer will never be able to match the input of the complexity of a real human player. Not sure why you can't grasp the concept of wanting to branch out, and play a game with a friend that might not have that game, unless your friendships are based strictly on specific games, which would be unfortunate, and i sincerely suggest trying to mix up what games you are playing with your friends, you'll have a blast.

Halo did suffer for split screen, and i did say that. But they did it to where they pushed the game too far for multiplayer, so singeplayer didn't suffer as much. (Frame rate drops are very noticeable. But, competitive is different than coop. Coop is more resource intensive. So while Halo's competitive multiplayer didn't suffer as much, the coop most definitely did. But you can noticeably see problems in Halo when splitscreening. But nothing I'm going to say is going to make you have any kind of revelation, so I'm done anyway.
