Played it for a bit, I'm not really interested in Blast Ball itself, but I loved the training for Federation Force. LOL at the people who complained Federation Force had nothing to do with Metroid Prime: as said pretty much everywhere, it plays exactly like Metroid Prime, with gameplay refinements and team elements added. The hold R + gyro à la Splatoon adds tons of subtlety to aiming and combat, and the use of heal elements is interesting. The combat against holo pirates was already more nervous and fun than combat in the original game.
The Gyro aiming + lock-on reminds me more of the Wii controls for the Prime series. It's really neat.
