I would like to start by saying stop providing statements like "this topic is awful" and "What is the point? Omgz you failz." He can argue on whatever he wants.
Ok... Tom Nook. I support him, I suppose. Do I believe he will get in? No.
If Brawl featured a character from AC, imo it would be more likely the AC human, because that's the character we all used from the game. Secondly, Tom Nook is a shop owner, not a fighter. What would he do? Throw paper at us and make us pay bills? Um... lol?
As for the backround statement, your ignorant to use it as proof for either side of this discussion.
Finally, what if Brawl was open to 50 characters or more... There is such a vast list of possiblities, i've heard hundreds of possible characters. If you don't believe me, read the 'Smash it Up' series on IGN's brawl page. Now this is purely opinion, but how important is Tom Nook? Would you really think of him being in a roster that will be broadly around 30-50 characters, of which most character's are either playable in some game or featured there own title? Eh... Tom Nook doesn't really matter that much. In fact, using your logic, LavisFiend, you could very well use one of the generic villiagers of or townspeople. Just something to think about...
