Mario games:
- Game altering gimmicks such as the FLUDD( from Super_Mario_Sunshine ) and ghost sucking vacuum( Luigi's Mansion) actually enhance gameplay(not allays true for some sonic games)(+ 10 points)
- Have more levels(+ 2 points)
- Are better platfomrs(+ 5 points)
Sonic games:
- Fast and furries levels(+ 10 points)
- Usually have better music(+ 10 points)

Sonic wins but that does not mean that Mario games are "bad", I just like Sonic more.
