Long story short.
When i used to play Super Smash Bros., it was fun enough to play with less than 10 aviable stages, 12 characters (i didn't know Ness and Captain Falcon at that time though) and against CPUs 95% of the time, it was fun enough because i had some of my favorite Nintendo characters in one game, fighting each other and at the same time having lots of entertaing moments.
When Melee was released, things got even better with a roster that had over 20 characters. Like before, some unknown characters were introduced, like Marth, Roy and Mr. Game & Watch, besides them, other great characters joined, like Mewtwo, Bowser, Ganondorf, etc.
When Brawl arrived we got even more new Nintendo fighters, such as Meta Knight, Pit, Lucario, Ike, Lucas, etc.
But what was new about Brawl's roster was two characters in particular: SOLID SNAKE Brawl Trailer
I didn't know anything about him, nor about Metal Gear Solid, so i couldn't share the joy many other Smash players had, but like they say, the more, the merrier.
Honestly i had mixed feelings with this character, sometimes i thought he was neat and very dangerous, other times i just thought he was really annoying because of his weight and powerful close combat moves that had big priorities.
Other than that, with the amount of third parties we have at the moment i wouldn't mind if Snake returns, as long he has more balanced moves than in Brawl. SONIC THE HEDGEHOG Brawl Trailer
At this point, i didn't have the chance to play the classic Sonic games yet, but at least i already played the ones that were released on the Game Cube and on the Wii, so i already knew the character and franchise, and therefore i was very excited when he was announced.
It was crazy to see how one of Mario's biggest rivals was able to join and finally was able to face the red plumber in a fight. At the same time though, maybe it wasn't very surprising since at this point Sonic already had some connection with Nintendo and their consoles. 3DS/WiiU Trailer
I actually doubted about him returning to Smash, but he did. I was very happy for the Blue Blur returning once again to fight the veterans and newcomers, and for SEGA, for letting this big moment repeat once again. MEGA MAN 3DS/WiiU Trailer
Now this was a big surprise that Sakurai threw at us as soon the new Smash was announced.
Mega Man, the Blue Bomber actually joining Smash Bros.? wow.
I know this was around two years ago, but even then i wasn't a big Mega Man fan back then, the only games i've played were MM2, MM6, X5 and Network Transmission. Up to now i've made some progress in playing his games (i still have to work on getting to play more games of that franchise though).
It was great to see this character that was pretty much abandoned by CAPCOM joining Smash, using his Mega Buster, Rush and Robot Masters abilities to fight the other fighters. He truly needed to join to rebump his franchise/popularity and actually, in my opinion, it was about time he joined this franchise. PAC-MAN 3DS/WiiU Trailer
A very iconic video game character since 1980, such a classic, simple character that evolved through the years (not a fan of his most recent look though).
Makes me remember when i was a kid an got to play Pac-Man, it was fun and that little theme that plays when you start a level, that's one of the jingles that are stuck in my mind since my very early years, just like the Overwolrd theme of SMB.
I'm glad he somehow got to join the roster, it's very nice to have more retro characters as playable fighters. RYU 3DS/WiiU Trailer
This guy. This, guy. Another iconic video game character since the late 80's. I wasn't into Street Fighter at all, but i knew the franchise, i played few of the games, the one that i remember the most is Alpha 2, or 3 iirc (kinda makes me want to get the Alpha SF that is on the Wii U's VC).
I also found Ryu in other games like MvC, he's been always one of my favorite characters in that franchise, along with Spider-Man and Shuma Gorath. I also found him in Tatsunoko Vs Capcom but i used other characters in that one.
With CAPCOM already adding Mega Man i never thought i'd see Ryu joinin, too. Two CAPCOM reps? the heck? but sure, why not. Another reaction i had was like "Ryu? joining Smash? am i dreaming?"
What can i say, it's awesome that Ryu is in Smash with a moveset that is like the ones he has in his games (not to mention the Shoryuken and Hadouken, that'll teach some characters that uses similar moves), and he's so far the only character with two different Final Smashes, though i wish his Shinku Hadouken was like the ones he makes in MvC instead. CLOUD STRIFE 3DS/WiiU Trailer
Square-Enix joins Smash!? Sakurai, you're a man full of surprises.
This has to be the biggest reveal so far in this game (it wasn't even leaked), Cloud from Final Fantasy VII, a game that was released only on the Playstation and that in the end didn't have much to do with Nintendo, regardless of Nintendo having the first 6 FF games on its consoles.
While some people wanted/expected Sora to take the slot, i had in mind that Cloud also had some huge chances to be selected if SE joined, and that was the result.
Even though i never played FFVII (or almost any FF game), i knew a little about Cloud back in the time, very little if i do say so myself, i only knew him from sight, other than that i didn't know the character itself or the game from where he comes.
The only game i have that has him (though it doesn't help much to know better of him) is Theathrythm Final Fantasy: Curtain Call (hence the pic above).
I'm not a big fan of him, but i do recognize him as a good character and as someone who deserved to join Smash, after all he's pretty much the mascot of the Final Fantasy franchise.
With all of this said, i know Sakurai is doing an awesome job with the DLC characters, so whowever else comes next time i'm sure it will be another great addition.
And with the current roster we have at the moment, i just want to say, what a time to be alive.
