It's called challenge. A strange concept for a Pokemon game I know. To address your points.
You could evolve Pokemon once they were purified.
You also couldn't trade in FRLG(To other games) until you cleared the
post-game
, and people don't dunk on the game because of that.
And while the Shadow system does have its flaws in Colosseum, it's not so bad as to make the game unplayable. I honestly get the feeling that some people were just upset they couldn't easily overlevel a Pokemon and press A until credits.
Limited Pokemon? Yeah, how many people used mons they normally wouldn't because of tthat?
Also yeah, absolutely try out XD. It addresses the main complaints of Colosseum. More interesting Shadow Pokemon mechanics (Multiple moves outside of Shadow Rush), type effectiveness interaction makes Shadows more threatening and makes not purifying a viable strategy.
Speaking of purification, it's way less annoying in XD too.
