Can somebody please tell me how Metroid would ever be online? It's a single player game...what are you going to have? A bunch of different colored Samuses shooting eachother? In order to have a good FPS, you need to have different characters to use...Metroid is Samus, that's all. Unless you count the enemies, but for me, fighting as some kinda alienoid wouldn't be very fun.
I want a Mario Tennis, Mario Golf, and a good, real life FPS. But as for the confirmed titles, I'll probably pick up Mario Strikers, and I'm definitely going to pick up Battalion Wars.
