Super Mystery Dungeon is looking so good based on what I've seen on YouTube. I feel like it could become the first spinoff Pokemon game that I actually want to play, the terrible thing is that my region has to wait the longest for the release. Having to wait until next year sucks, but when it comes out I will consider getting it for a late birthday present should I not get anything worthy this year.
I'm sure you know what Pokemon I will be playing with (you can actually either go with the Pokemon that the personality quiz suggests for you or choose the Pokemon yourself) but I'm debating my potential partner choice. I would have picked Riolu but I've now been seeing that it's likely a lot of people here are going to use him so I'm considering a Fire-type starter as my partner instead, one that's not going to be overused so much.
I noticed you plan to go with Oshawott on your first playthrough but then I presume you will be sticking with Froakie after that.
