Most of my digital download things. Pok?mon Yellow aged bad and, well probably one of the more overrated games in the series. Also Pikachu really suck as a starter and you have to focus too much on training up other Pok?mon. And they removed the Mew glitch :c
Code of Princess or whatever the game's name was. I've yet to play a really good fighting game on a console, most are too small for it. I prefer playing those on arcade machine... not slamming buttons randomly like that.
Codename STEAM. It's not really bad, just the formula (Fire Emblem-esque) doesn't go with 3D environments. It also starts off really hard at first and the tutorial sucked. I still own it though.

Actually, they didn't remove the Mew glitch! If you're talking about the one where you use teleport near the Nugget Bridge when a trainer pings you (and you narrowly escape the battle by pressing pause and using teleport), it's still there! I have a Mew because of it, but I'm going to assume you can't transfer it to PokeBank.
Fantasy Life. It's cute and a decent time waster, but my god, the cutscenes take forever and there is entirely too much text. I got frustrated by the amount of times the game stopped me from doing things or limited me just for the sake of a bland story.
