Goldeneye 007 for the N64. Halo (although I hate to admit it)... and most fighters in general. I've had the most fun playing one-on-one of Free-For-All multiplayer games. Team play is fun for a bit, but it seems these days that all the big AAA shooters and some fighters even, are just focused on team play. Some games like Battlefield don't even have a solo multiplayer mode at all, lol.
Team play and FFA play are different. One isn't "better" than the other, but most people like one over the other anyhow. I like being part of something to achieve victory, but it also feels good to show one's prowess when its you against the world.--Or in a
1-on-1 duel. Gamers these days get too scared if there isn't a mode that allows you to linger in the back and camp.
What does everyone else think?
