My turn now! I'll probably say Super Mario 3D Land because I got bored after playing it for 10 hours.
Another one would be Pokémon Y since I can't seem to enjoy the fights, trainings, and I don't have any friends aside of my sister, which never wants to duel me, so it's quite boring after a while.
Also, Project X Zone is a suite to Namco X Capcom, so it HAD to be similar in terms of plot, gameplay and design, except with a little more 3D.
Also, I'm not a fan of Kid Icarus - Uprising, or Animal Crossing : New Leaf, but I can't complain since I've never bought either of them (I'm not really a fan of Kid Icarus or Animal Crossing).
