So I did the first map of G Generation World to see how the series plays.
Pros:
+dialogues between bosses are voiced (SRW should add this!!)
+building a team of gundams to take into various stories across gundam universe sounds like it could be interesting
+the whole chance step stuff seems neat
Cons:
-No button to change to the next still-active unit? What? This is like essential in srpgs and I can't seem to find it so I have to search the field for non-turn-ended units left to use.
-I don't like how enemies don't have reactions to getting hit/dying. I miss the SRW thing where they go BLAAAARGH YOU GOT MEEEEEE and then proceed to explode.
-man I miss seishins from SRW when my hit percentage is like 50% and I don't just have a spell to up it to 100%

I hear they added seishins in G Gen 3D though, so I'm guessing eventually the series will be even closer to SRW.
Seems interesting. When I get around to playing it I'll need to read some guides as to how to approach and play the series.
