One Piece: Romance Dawn has some potential, but the long drawn out cut-scenes and lack of difficulty in the combat drags it down. Every level feels like it’s five to ten minutes of wandering around and fighting, then the same amount of time with the cut-scenes. Unless you’re a huge One Piece fan, you might want to think twice before picking this one up. It’s not terrible, but it definitely has its flaws.
Mario & Sonic at the Sochi 2014 Olympic Winter Games isn't all that bad, but it's not great either. The controls for a lot of the events are iffy at best, but there are events that are still enjoyable, especially the Dream Events. This is one where I'd check out the demo or rent it first to see if you like it before plunking down $50 for it.
Pokemon X and Y are definitely two of the best games in the series to date. The new features are fun to play with (especially the PSS), and the Mega Evolutions and new Fariy-type changes things up with the type-matchups. Whether you’re a veteran or just starting your very first journey, Pokemon X and Y are definitely worth picking up.
