Finally got this along with Gundam Breaker 2 as x-mas gifts. Played around for a bit and
Like:
+Speed increase, feels like turbo mode
+Fleshing out the existing units so everyone has a full movelist now
+The new music, since launch it seems like they patched Premium G Sound so it uses all the songs and you don't have to replace tracks for the bonus 35 tracks
+Arcade mode - Seems more meaty now
+Main Menu, like how you can jump straight into online or SP
Neutral
+New units, coming from Extreme Vs + All DLC it's a decent number, but lots of them are grunt/alteration units. Not a lot of new main character units.
+New graphics shading, not sure if I like. Extreme Vs. looked cleaner
Dislike
-Man, wtf happened to the single player mode? Ex VS mission mode was really good with the branching paths with good difficulty pacing. But now it's just a list and more importantly you don't get generic points to spend on any unit so everytime you switch units you start back at zero. Just feels a lot more low-effort than Extreme Vs.
Anyhow, just getting a feel for the new stuff and already looking forward to Maxi Boost because I prefer the new cast additions in that one + hopefully they'll do a nicer single player next time.
