Be warned. This could be spoilers for those who haven't play yet!
There are things you hope you can do it in Pokémon Mystery Dungeon Gates To Infinity but you can't.
-Using Trawl Orb to rob Kecleon. I never get bored of this.
-Linked combo attacks which I can utilise and swiftly defeat bosses.
-Alot of legendaries recruitment.
-Pokémon that can phase through walls. Useful to run away.
Though I do not mind the lack of other Pokémon recruitment and the insanely tough 99 floors dungeon, I really miss the others I mentioned. So I played the older PMD for nostalgia.
How about you? State the things you missed that you can't do in PMD GTI.
