Steam Games: Hitman Collection, Agarest: Generations of War and Mercenary Kings
3DS Games:
Zelda: A Link to the Past - My first Zelda game I have ever played. Its not a bad game, but I'm just not a huge fan of the gameplay.
Donkey Kong Country Returns - I thought that the controls in the game were alright. My main complaint is that it felt like I was playing on ice every level, Donkey Kong was sliding all over the place. That or maybe I'm just terrible at this plat former in particular.
Pokemon X/Y - I played through it. I had fun with it. However, I prefer the older games better since I'm not particularly happy with the 3D aspects of the game. I actually like the older versions of Pokemon better for that reason.
I don't regret but I do have a problem with:
Super Mario 3D Land - The ONLY problem I have with this game is the jumping which did make the game more challenging. Yes, jumping is probably the most difficult thing about this game. I can't really put it into the "Regret Buying" list because at 600 coins, I already own the other 600 coin games and I don't own a WiiU console so I didn't really have much of a choice with my purchase as I didn't want any of the games under 600 coins.
