GTI was definitely not as good as the explorers games. The story line, and especially the after story, were way to short in my opinion. Building up paradise was fun though. The whole concept of the magnagates was amazing, I just feel like they could've done better with it. And then there was the fact you only had 4 choices of pokemon to be and it didn't have the personality test seen in the previous games. That really annoyed me. They brought it back in PSMD though, so hoorah for that.

As for hording treasure, I got to the point where Even my storage was full. You just have to pick up every item on the floor that you find or you're not doing it right.
