To be honest. Eyetoy compatibility was huge on EXUS because it was a mystery and had a cool concept. Then it came out and it was okay for awhile, but nothing spectacular as expected.
Then EX2 came and it lost popularity as it was the same stuff as EXUS with less of the game modes.
Then SN1 came and no cared.
Then SN2 came and people are saying "why the hell is this still even here it's just taking up space for other stuff they can add to the game".
So yeah, you'll lose interest soon. I thought it was really cool also, then about a day or two later i'm like "wow this is gay".
