I bought the 3DS Striker Pack last holiday season. Gunvolt 1 is a great game with a lot of replayibility. In particular, Gunvolt is a really fun character to control. The game really demonstrates the expertise IntiCreates built up working on the Mega Man series. I would recommend Gunvolt to anyone who was a fan of IntiCreates's previous Mega Man games.
I still haven't found the time to finish Gunvolt 2 yet, though.
Since the 3DS game was created with emphasis on the visual aspects of the game, it was only able to run at 30 FPS on that system, but thanks to more powerful new hardware, 60 FPS Gunvolt is here for the first time. The biggest difference between the former 30 FPS and the new 60 FPS can be felt while playing as Copen, the super-quick, high-flying playable character from Gunvolt 2.
Was kind of hoping they'd add the ability to play as one of the many cool looking female characters they have instead of only having the choice of dude or dude, but I guess I should check this out anyhoo :3
