Funny you should say that, Eich~ because I absolutely HATED Black/White... enough to stop playing around the 4th or 5th gym and not even bother with B/W2... so I was really hesitant to pick up X and Y, but it seems like they solved most of the issues I had with the previous iteration.
B/W did have a lot of problems, I'm just not very picky. Y was particularly good, though. Plus, they introduced Aegislash is X/Y, who is a lot of fun to play with.
*Comes out of hiding* Is Pokemon that cool? I've never had the chance to play it...
They're quite fun, yes. I played competitively over the summer a little bit. They're great for something cute and easy, or something challenging and demanding (and still cute), depending on what you're looking for.
