Obviously this is the only thing setting this apart from Smash Bros, but with that said, it's a pretty huge thing. As someone who has played the Beta extensively, I have to say that the Super System is conceptually better while the Knockout System is overall more fun.
The Super System
Giving each character 3 super attacks is awesome
Staying out of the fight is not a viable option
Kills get stolen much less
Only 1 way to kill might get old
Unbalance in Levels across characters
More to learn and master for each character
The Knockout System
Easier for anyone to pickup and play
Diversity in your kills
Final Smashes acting as Super attacks are awesome
Planning out your kill is more fun
After damaging a player a lot your kill can easily be stolen
Can stay out of battle to avoid damage
Smash Bros system is the defining Brawler system for me, and my love for it will always keep it above the Super System, but for a game that is trying it's hardest to be different from it's inspiration, I commend the Super System for trying something new. I continue to play Smash Bros for hundreds of hours and my worry about limiting the ways to kill is that it will also kill the re-playability factor of the game
honestly, if smash had a AP bar instead of a crazy fight to get a flying orb for a final smash, i think it would be better.
Also think that the learning curve for characters in this game is more of a pro then a con and gives the game more re-playability in the end.
The fight for the Smash Ball was half the fun. Whenever it came out things got hectic and that made it all the more better. Also, I'd have to disagree with that. In Smash I was able to play so long because I mastered every character easily and I had 35 (25 in melee) characters who I'd play as, whereas in fighting games with steep learning curves I normally can only get good with 3-6 at a time and then I get bored with them and stop playing sooner.
Dude, smash only has 1 way to kill too...-_- and it still is fun
You obviously didn't understand what I was saying. You could use any attack you want to kill and any item and any stage obstacle. Where in this you only can use supers, that's a big difference. It makes the smaller attacks, items and stage obstacles seem to just be AP builders and you use whichever builds the bar quickest.
if super smash bros 4 gets a super meter bar (smash bar) along with the percentage based fighting this game will be for the birds lol. it's a chance they might just do that.
