I played it after years of not playing and I did enjoy it. I think the highlights are Career mode, which may be a season mode more or less since its main story is about "one year," with the post-game if you will, as well the creative suits are very in depth and very very fun to make characters. Like, I made an entire thread related to making CAWs and you can create a variety of characters, the arenas once you get good at, can be pretty cool, then titantrons, etc.
Universe mode is decent in concept, but I always find myself resetting it multiple times. However, it can be a decent time-waster. As well, matches tend to be pretty good as a whole and I think is the best its been for the game's attempts at creating a Simulation engine with some room for arcade-ish moves with the Payback features.
