The Good:
Kamen Rider: SummonRide for the PS3 plays fairly well as a fighting game. The graphics are good, if unremarkable. It's happy to play in an US PS3 system and can even grab update data from the US. It's also good if you're a fan of the "Masked Rider" series as the game and the collectible characters are from that series of shows.
The Bad:
If you can't read Japanese, you're probably not going to enjoy the game very much as most of the game is written and spoken in that language. It also seems a bit slow to load levels and is also a bit slow in recognizing the play pieces on the portal.
