I have Red Rescue Team, and that's it... I haven't played the Gen IV ones actually.
However I have played the one I have to death. I have every legendary recruited (Mew gave me the hardest time.), so many level 100s (including a Caterpie), Platinum Rank team, all the statue/figurine/whatever things, etc. And the story was awesome, heart-tugging 'til the end, and even after. I was so sad when I learned about Gengar's origins, and Gardevoir losing her memory... Typing all of this makes me ask myself why I haven't picked up any of the newer ones wtf am I doing?? Are they good?
