Oh, yeah, I forgot about Super Sonic. Well, I guess if Megaman has time to defeat the Robot Masters, Sonic has time to collect the blasted Emeralds. So let's just say Mario has a fire flower or star he got out of the "?" next to him and Sonic and MegaMan are completely unprepared. lol
Dude, I don't even know. Maybe they'll all wipe each other out? My money would be on Sonic as the others wouldn't know what hit them, but those weapons from the Robot Masters and Mario's power ups could even the play field, but just to be fair Sonic has a force field bubble. All I know is that there's going to be 8-bit heck to pay. Or 16-bit for Sonic. Whatever.
If we are talking about these three with just their standard arsenals (Sonic just with his speed, spin dash, and light speed dash- Mario with his SSB moves- Megaman with his buster and a random Rush ability) hmm I'd have to sadly say Mario's out of his league and it would be rather close between Sonic and Mega. I'm kind of wanting to say Mega would win between these three due to Sonic's tendency to be sort of cocky when he's feels he's in control might work against him.
I may not like his game the most but, Sonic has this one easy. He can dodge anything the other two can throw at him punch them each in the face 1000 times and then have a few chilli dogs before they even know what is happening.
"Sonic's only good games are the ones with Mario in them."
I'd agree to this as the percentage of Mario games that are good is much higher than the percentage of Sonic games that are good, but Sonic and Mario did star in three games together and I've only heard bad reviews for those games. Oh, except Smash Bros. Brawl, the 4th game they were both in. That was the only good one. I'd like to point out now that Mario and Sonic at the Olympic Games, Olympic Winter Games, and Olympic Winter Games DS were all developed by a SEGA company whereas Brawl was developed by Ad hoc development team. I was going to say Nintendo, but I dunno if that group is outsourced or within Nintendo itself. Either way, I think you'll see my point as to why Sonic games tend to suck. Fortunately I think this next chapter of Sonic will hopefully make me stop saying that the best Sonic game I've played since my childhood was Super Smash Bros. Brawl. Which is very sad. Come on, Sonic. Up your game!
Sorry, I was a little negative when I wrote that old comment. My favorite Sonic games were most of them between Sonic 1 and Sonic Adventure 2, namely Sonic 1, CD, 2, 3, S&K, SA1 and SA2 (hold the Spinball, Mean beans, and 3D Blast). Heroes was a little too light hearted after the awesomeness of SA1 and SA2 especially but proved to be a surprisingly enjoyable game. Shadow's game had its moments but ended up being the only Sonic game I've ever sold in my entire life. Most Sonic games past that were mostly forgettable, although Sonic Rush and Sonic Rush Adventure to me were a return to better gaming. I thought Sonic and the Black Knight was actually good, if not horribly difficult to beat the later missions, and Sonic Unleashed was a step in the right direction, although SEGA's promise that it, much like their promise for Sonic 2006 ("Sonic and the Rings of Disaster" to me, ha ha), would return Sonic to his roots was not delivered and was a disappointment. Today in 2011 however Sonic Colors has been an excellent title (although I feel like it was still missing ... something), Sonic 4 was short but wonderful, and Sonic Generations may prove to be the best Sonic game since the 90's (graphics keep improving in Sonic games, but I'm speaking of best game play and overall enjoyment).
I also found out that Brawl was worked on by the Square Enix people as well. I think they worked on the story line of the single player adventure mode. Anyway, hey - love to see HAL Labs do a Sonic or even Sonic fighting game! You know that'd be interesting.
