My impressions after about an hour of playing:
Overwatch mecha version

90% similar, nothing unique to Gundam. Kawaii anime characters were also not seen. At least for me I couldn't able to find a reason to play.

Until this game is properly released, it would be great if they could create something unique to Gundam other than Overwatch.
It would be nice if the anime characters could somehow involve in-game themselves, like Super Mecha Champion. Don't get me wrong, I used to play Gu
