Smash is only a platformer in nature when you play that one story mode in melee or SSE.
Let's look at it point by point.
Each character (while having similar directional inputs) have different attacks that combo or 'combo' differently depending on the character.
Street fighter has that same action. While inputs are somewhat different, there are similarities (jab, short, roundhouse, etc. all work the same for each character, while frame data might be different). Street fighter has more inputs than smash yes, but they work generally the same way.
Street fighter and Smash can both end in time-out, or 'k.o'. While the stock system is different than the life bar system in the sense that if your opponent is an idiot, you can live for much longer than you should, It's still generally the same. Yes, certain characters die at different %'s than others (see; snake dies much later than jigglypuff), the same can be said for street fighter (zangief dies MUCH later than seth).
A fighting game is generally knocking your opponent out before your opponent knocks you out. With items it can still be considered a fighter, just different mechanics.
I remember at final round Jwong was ****** some people with Diddy Kong a LONG while back, got 2nd place at that tournament if i remember right. Justin Wong has great spacing and general fighting game knowledge, to say that he would come into a party game with that knowledge and still place well wouldn't make sense. Brawl/Melee both have spacing and zoning tools such as street fighter. The game is broken sure, the mechanics are a bit different, i agree with that as well, however the idea that it's not a fighting game when we've made rules that give it a fighting game-esque feel is stupid to say.
Sorry to say brawl players, but melee is closer to a 'fighting game' than brawl. In the sense that melee has 'combos'. While brawl also has them, they are pretty silly.
No need to bash one another though, just accept the facts.
btw tommy_g, don't try to defend yourself with only thoughts and assumptions, it generally makes you look like an idiot no offense. I see what you're trying to say though

but when did Nu get banned from blazblue? She's not even the best character.
