i like team a lot more, since ffa is all about stealing kills to win, but not much strategy, other than get behind cover when ur a one-shot. in team games, it takes a good strategy, skill, communication, trust, and team-work. even if your not that good at getting kills, you can still help yur team win with clean-up, support, being a distraction, or just calling out. ffa is just luck with some good marksmanship, while team is having some skill, at halo.
