Playing four player games nowadays on one TV using one console is very very normal. But back when we had a PS1, four player games were very hard to come by. The norm was 2 player modes (for versus games and some side-scrolling action adventure games) and 2-player split screen mode (for racing games and third person games). The console was able to provide four player goodness if two PlayStations were connected via System Link. I never tried out this feature though. I never bothered with it... What about you?
