Got it on the 30th I like, A lot better than the 3rd one, more fleshed out, and online play! I don't think I would be playing it much without the online play, and the customizable characters. I've always been a fan of the SC series, but haven't had any competition.
As far as gameplay, way different that Melee, but that doesn't mean it's a bad thing. It's more traditional in the fighting game category. It's got kickass characters and kick as moves. Like the guy said earlier, it's like tekken with weapons, but there are still many things that make each their own. I tried getting into but Tekken, but SC is so much more kick ass. As far as tourny play for this game I dunno how the elite have ruled yet. I know the second and 3rds ones were said to be way too broken.
Either way I would highly recommend, it's an amazing game. And if this is your first, you'll be blown away. It's a really intricate game with a well balanced fighting system but also button smashing "fun-ness". I guess in a sense, it's very similar to Smash 🙄 Go get it!
