Before I got Brawl, I was itching to try out Ike, Snake, and Wolf. So far I've only used Snake and Ike out of the three, but I haven't gotten into either.
Instead, my favorite characters have been Pit and Diddy Kong, which is quite surprising since I had no interest in either before getting the game. Out of those two, I definitely prefer Pit, as he's my best character. I enjoy playing with DK, but I always get my ass beat with him. ^^
So, who are your favorite characters, now that you've actually played the game?
