The reviews for Mystery Dungeon 1 and 2 were not that hot either, so I can that I won't be trusting any of these, since Dungeon 2 is one of my favorite games.

If you liked the other titles in the series, I can't see a reason for this title being about just as good and I am pretty danr excited for this game aswell.

It's a roguelike, isn't it? (Or am I mixing it up with something else?)

I'd imagine it'll be one of those things where it's like "if you like the genre, you'll enjoy it".

I agree with that. I saw that the other two got some really mediocre scores, but the meat of the games for me is the charm it has. The writing is the best of the Pokémon series, but the gameplay is very repetetive, although you could use different sorts of tactics, but it is very limited. I am mostly excited for the writing and the soundtrack. Too bad that Europeans (me) won't be getting this  game until around the end of May.

OP has been updated to be less clustered.
