I posted this becuase they're are many things wrong with this generation, but its not a bad game at all. The worst thing i can think of is that they made groudon, kyroge, and rayquaza have rest in their list of moves instead of recover.
Rayquaza is a sweeper he does not need recover. He has to deal as much damage as he can and as fast as possible while it using recover another rayquaza (or another sweeper) with ice beam will kill it. They aren't able to recover like Lugia or Mewtwo but they are still super powerful (ubers).
well although I do miss day and night I also think they should have had different sprites for each version just like in the R/B/Y/G/S/C days. I know it was probably to many pokemon to design a different sprite for R/S/E/FR/LG but I really miss that. Now I know the Kanto pokemon have different sprites in FR/LG than in R/S/E but what I mean is that they would have a different sprite for Ruby than FR/LG/E/ and Sapphire for like mudkip and A different sprite for bellossom in FR than in R/S/E and LeafGreen. So what I am basicaly saying is that I miss when they had a different sprite for each Individual version.
