Thank you ladies and gentle-smash brothahs for your lovely and kind words. With that, I leave you with this: which came first, the chicken or the egg=???
The answer you ask=??? Something unexpected came first... THE CHICK!!!!
(sorry, I saw chicken, and I had to do it! XD)
Also, how the roster plays off each other, and how the roster "balances itself" out. What I mean by that is, why would Sakurai want all fast swordsmen when he can have characters with swords, magical powers, punching power, kicking power, or other strange abilities as well=???
Also, why would Sakurai want only heavy, extremely strong, slow characters with crappy recoveries when he can have fast characters light characters, weak and fast characters with great recoveries, as well as other random combinations, like heavy, weak, slow characters with incredible recoveries=???
Smash bros, more than any other fighting game franchise, is blessed with incredible character diversity, which helps make each character and each smash game feel more and more unique.
