XvSF is a pretty fun game to play for short periods of time when you're bored. It's fast paced on Turbo mode and there are plenty of moves and combos to figure out.
But if you're looking for a Capcom game which tests your skill, this is NOT it. It's ridiculously unbalanced. There are some characters which just slaughter all others, such as Cyclops. Cyclops' ranged attack instantly cancels out all enemy projectiles and hits the opponent, moving way faster than any other projectile -- plus, it has very good recovery time, can be done high, low, or as an anti-air, and can be fired from the air as well; Cyclops is also extremely good at melee, good enough to knock his opponent far away and continue blasting them into pieces. Juggernaut is also way too strong, and a team of those two can obliterate all opponents.
Other than its imbalance, though, XvSF is fun if you're looking not for a challenge but rather for a way to relieve some stress.
