I have played the demo for Pokemon Rumble and found it entertaining. The battle system reminds me of 1980s style computer games. 

But before I pay $15, I want to know if anyone has bought it and what they think about it.

Thanks in advance.

Im have Pokrmon( I seem to be the only one).... This a fun addicting spinoff to the Pokemon...If you loove Pokemon you wont be disapointed, BUT i recommend you play with other,,it can very later on in the game

it's certainly long enough, like 15 hours. just depends if you really like the battle system enough, and won't get bored of it.

i say no. way to repetetive. doing the same thing over and over and over anddddd over.

not worth 15 no. I would have been happier if it was 10 or even 8. Doesn't have all the pokemon. No leveling up. Only two moves per pokemon. What you catch it just random. Very few levels.
