^Hm, that sounds like a good idea; however, what do you think it would be based on? I'm still hoping to see a RPG game with the actual Mario characters in it as opposed to exclusive characters (such as the Paper Mario characters/partners). I believe you mentioned this earlier on another thread, and I found this idea to be quite interesting. It could really diversify the Mario series and its actual characters.
In SPM, the characters were Mario, Luigi, Peach, and Bowser. If only we could add Toad, Yoshi, Donkey Kong, and Wario into it (+ a more 3D layout); a really interesting game could start up (perhaps more characters as well). Perhaps a game that explores different Mario locations such as the Mushroom Kingdom, Yoshi's Island, DK's Jungle, and so on. I like the Mario & Luigi series; however, I think that it is time that the other major characters (aside from Mario and to an extent Luigi) deserve more attention to being in the Mario games...
