This is a game I'm very interested in, It's an RPG that's coming out in a few months time that's quite unique. Instead of using magic and tradition attacks and such you attack with different guns and instead of navigating menus it's more action-based. I played the Japanese Demo and it's quite fun although I only really understood the basics of the gameplay. Here's a trailer and soem battle gameplay (since it's difficult to explain).
^The gameplay starts around halfway through.
It's a weird game to explain but I found the demo quite fun.
