I just beat XD last night. It has its pros and cons over Colosseum.
>I got used to backtracking in Colosseum - having to walk out of a dungeon to heal up then go back in - but XD is more generous with healing stations within dungeons>Colosseum's regular trainers were much harder than XD's, I got wiped by a generic or two early on in Colosseum but never lost a battle in XD until the very end of the game>purification is much faster and easier in XD, since you can work on purifying 15 Pokemon at once - the worst part about endgame Colosseum was purifying everything to trade them over to the GBA games to put them in Box>XD has a better, more interesting story, and missed shadow Pokemon are both easier and more fun to get>you don't have to do fucking Mt. Battle to get Lugia>>37491971And three Pokemon that you can trade wild Pokemon for.
Interested to hear about the extra post-game thing you can do. After the credits rolled, all I did was trade in a mon from Ruby and one from FireRed to wipe out Miror B. again.
