Never played a Mystery Dungeon game. Right now, I have 4 games I'm trying to decide between for my next purchase. They are Etrian Odyssey IV, Shin Megami Tensei IV, Soul Hackers, and Link Between Worlds (I realize that 3 of those 4 are Atlus RPG's).
I think the tier list I read was based on gen V. I'm not sure how much movement between tiers will happen due to new abilities and mega evolutions of this generation. Hopefully my Ampharos will get a bit more love with her mega evolution. Not sure how I'll do my first team since I haven't played competitive before. I figure I'll start out with a couple of my favorites then add more Pokemon once I know what I need for my strategy.
