I haven't picked it up. However, I've watched a few story walkthroughs. The arena battles hearken back to Digimon Rumble Arena, but with new Digimon. Between arena matches, however, it's a bit like Digimon World 4/X. They minced translated attack names (ie- Agumon's Pepper Breath is Spitfire Breath), and the story isn't much, but if you beat the game and unlock all of the Digimon, it would be a great game to play for parties.
