Usually I will buy the new game, finish it in a day or two, play it for like another 2 or 3 days, and then never play it again. Don't know if I will get Alpha or Omega but probably will not. Then again I said that for X and Y and then got X.
I'm kinda like Jacen there. I'll play it for about 2 months, then never play it again, although I sometimes go back and play pokemon now and then. The latest pokemon I have is Black.
I'm a pokemanic, I've played gen 3 to the current generation, and I play when ever I get the chance. I own X, and I'm going to buy the new Sapphire when I comes out, because Sapphire was my first.
I've played up to Pokemon White 1 and I don't really want to get a 3DS. I borrowed a friend's 3DS and played X/Y. I might borrow for omega and alpha too. I play Pokemon Showdown but I haven't touched it since 3 months ago.
i usually play till i finish the story and get all (possible) legendaries. actually i havnt finished white 2s story and i kind of stopped playing already
