Like the other guys I'd go with split screen. But only if you know you are capable of the task. Too many times I have not finished a game because I've set my sights too high. But if you think you can do it then go for it. Split screen can offer up some fantastic gaming if done right. One of my favourite games was a splitscreen (Vertical) game on the Amiga called Knights. With a piece of cardboard down the middle of the screen me and my best mate would play for hours with no idea where the other guy was, it made for some fantastic gameplay. Those were the days. Anyway, look forward to seeing some screens. Good luck.
