Nintendo had a whole Pokémon Lounge set up at New York Comic Con this year, but I got so caught up in the events at the convention center that I never actually got around to checking it out (it was in a separate, but nearby, location). But during a visit to Nintendo's booth, I was able to get my hands on the upcoming Pokémon Rumble Blast on the 3DS.
There wasn't anyone nearby to tell me exactly what the game was all about, so I just had to wing it. It didn't seem very complicated, though. The top 3D screen is a top down view of a Pokémon you steer into various locations where you combat other Pokémon. It seems like you just sort of mash the one button to use your Pokémon's attack and take out the swarms of enemies surrounding you. I tried the other buttons, but they didn't seem to do anything. After working your way through the various areas in the location you entered from the map screen, you fight off a boss, and then move on to the next one. I did find out later that you're actually play a Toy Pokémon.
As you defeat Pokémon, you also collect them, because what would a Pokémon game be without collecting everything in sight? (There are 600 in total from all the games in the series) But beyond that, the sample I got didn't really demonstrate any depth or strategy. You can choose to fight as any of the Pokémon you've collected, so presumably you'll adjust depending on who you're up against. Being a Pokémon game, in addition to collection, there's usually some kind of strategy involved, even if it's just the usual rock/paper/scissors gameplay of choosing the right attacks that your opponent is weak against.
Being on the show floor, I couldn't hear any of the sound or music to offer an opinion on that, but the graphics were clean, and the top down view means that the 3D creates a nice effect of depth in the world. There's a multiplayer component where you can play with friends via StreetPass, but this was a single player demo only. I still wish there'd been a proper 3DS Pokémon game, but for now, this spin-off will have to do. I'm just not sure from this demo, at least how much more there is to this game beyond the button mashing
