I think I'm done with Championship Mode, at least for the time being, because I'm enjoying it a lot less ever since I reached the G2 division. G3 frequently offered a variety of characters I usually hadn't seen before like Seths or Fei-Longs, while G2 has been a significantly more boring affair so far. It kind of bugs me how most people not only play really conservative the second the match starts (not everyone outright turtles but still), but how they also do this with some of the better fighters at that. Characters that are good to great at offense. Yet at the start of almost every match (against total strangers), what do I see? Balrog / Ryu / Sagat / etc. players backing the fuck away against a frail character like Dhalsim... So stale and mindnumbingly tedious.
Oh, and another great thing. By the time I do advance to the finals, I practically always have to fight against the umpteenth Ryu. Exciting!
