Well, I got Paper Mario and have been playing it every sense. My general opinion on the game: Great. Another fun chapter to the Mario epoch.
I've played for over 4 hours and I haven't done much. I've only leveled up about 3 times, recovered only one of the Stars and gotten the Goomba, Koopa, and Bob-omb buddies. Seems like it'll be a long game. I certainly hope so.
The female Magikoopa's name is Kammy and she is basicly another Kamek. The Kamek-ish Magikoopa I saw in the screen shot is just your usual Magikoopa. As for Kamek, no where to be seen. Probably dead. ..Seems like he's the first Mario character to die (well..besides minor enemies). Luigi is in it...but not for any reason except to *be in in a game*. So far, he's not been important. He's gotta stay at home to "make sure nothing happens". At times you get to control Princess Peach. I don't know if Yoshi is in it, as I am not at the stage with Yoshis yet.
It's really an excellent game. The graphics are very easy to get used to and the music is pretty good. Actually, I think the cartooned characters make it much easier to see expressions and such. It makes the game more entertaining. However, it is obvious the complexity is toned-down for kids. Consider this more a RPG/Tradional Mario game mix. You have your basic ablilities (Jumping, Hammer) and your items..and, of course, your friends. They really should have made something better, I think it falls short of what we had with 'Mario RPG'. But, if you love Mario games, you'll love this.
