I probably don't like it as much as I liked Duel when I started with that, so i can't see me sticking with it anywhere near as long, but I'm entertained enough to probably get through the missions. I doubt very much I'll stick around the complete the Pokedex or anything, but we'll see. It'll probably depend how close I am when I finish the "story".

When you start out the game is generous with how long it lets you play but eventually you hit the wall where you get 5 games and then you have to wait a couple of hours for the "battery" to recharge so you can play more. That makes it very easy to just pick up and play for 5-10 minutes here and there.
