Mine is Prime 1, followed by Zero Mission, and then Other M. And yes, the gameplay is great, but I find too many people hate the story. My only problem with it is that Sammy needed a better VA who conveyed more emotion. But being the person she is, I understand the lack. Sammy WOULD have zero emotion in her voice and in theory it works. Just not delivery. I would have liked the taunting, bored tone she had in Super Smash Bros Brawl.
