Both of the games are very entertaining, but I favour the first one. Mostly because V-Gundam is showing us his really useful harass in the beginning with his scout SCV and his first marine. As we can see in this picture, Gundam does exactly that.
The third game is a friendly game with GroT himself versus ToS)Excel(. The special about this RWA is that it's made live. GroT himself says that the game's quality is not high level, and is only recommended if you really like live RWA's.
