1. More Unpredictability In The Backgrounds
How is this a good thing, especially if you're into competitive fighting? It just ruins the competitiveness of the game. And since you can't get damaged nor die being hit by these "unpredictable backgrounds," they're pointless.
2. Online Play Is Sure To Be Much More Convenient
How do you know? Did you play the online of the game? But just for the sake, if it does; then, great. It's great to see a game compete on an almost five years-old game.
"Note: Sony hasn’t one hundred percent confirmed online play...?" Nice one there. -_-
3. No Cheap Ring Outs
Uhhh... That's just ironic because PSASBR has a more gimmicky mechanic than the SSB series. Also, the other SSB games have Stamina Mode, where it gives all characters a sort-of life bar, which must be depleted to defeat characters, rather then KOing them.You can just create a custom cage-type of stage in Brawl and play the Stamina Mode, and you've got an almost standard fighting game with no "cheap ring outs." Nice try, but you don't know SSB games.
4. Cross-Play Will Really Open Up Competitive Play On Both PS3 And Vita
This is more of a disadvantage... I mean, if you're going to play the game with the PS3, why use a Vita instead of the huge screen in front of you? You could say that "what if there was no other controller?", but that still makes no sense because you have to buy two of the same game just to play multiplayer where you could have just bought another controller for cheap? That's stupid.
5. We Won’t See The Next Super Smash Bros. For Some Time
How is that an advantage? With the stupid mechanic, it will just throw off those Smash Bros. fans.
I'm not hating on the game since I might get it after it released, but if that's all the advantages; then, that's just sad...
