Mario or SONIC  

both are very good but if i had to choose it would be marrio as there were so many different vaiations of this game, i brought me sonic for the play station two a few years ago used to have it on the master system as a child

both are good game but if would ask me what i play most that would be sonic.since i play mario at age 7 kinda get fed up. sonic has the better graphics.

I like Mario better.

mario is a slightly better character. But games wise he is wayyy ahead of sonic. so its not a contest. mario ftw

Sonic!Because I love the feeling of speed!!!

i love sonic more.....lol....mario is just fine but i found it too dry...

I would have to say sonic because mario doesn't have anything new with it since the last 20 years it's been out, sonic always introduces something new every time a new sonic games comes out that's why sonic to me is an all time favorite.

I never liked Mario that much :| ,but sonic became my second favourite on my gameboy next to crash bandicoot :D.... And all the characters in sonic are funky,unlike mario that looks ugly :(

Both are good. But I prefer Mario series :) Bigger classic and more interesting, I think. The bad thing is that Mario games are very hard to play. The are too many joysticks I broke because of Mario who drives me crazy and makes me as nervous as I have never been . . . Ha-ha!
