theres not much to trade in for this game except for the 3 missing Gundams that you get when you finish most of the Story mode. I got the complete 100% MS gallery by playing mostly online.
-Musha Gundam (red)
-Musha Gundam MkII (blue)
If you want to get the cheevo early, find someone with those Mobile Suits and ask them if they can use it so it unlocks for your gallery
