I think Sonic games are fun, however, I'm always going to stick with Mario. Let's see why...
Well, this is weird, but my first system I ever got was a Genesis. I was 4 or 5. I liked video games, but not Nintendo in particular. Anyway, I didn't have a game system or handheld at the time so my neighbor let me borrow his. My dad never hooked it up, and thank God he didn't either. So we gave it back. Anyway, so I later got into Mario, blah, blah, blah. Anyway, go 10 years into the future and you'll see me playing the original Sonic on the Wii. Yea, I downloaded it. I love it too. The music sometimes...erm, is better than Mario. The platforming is kinda hard, but Mario has the better tight controls and everything.
