The fact that the only way you can kill people is with supers, and that there's not even an option to change it to, say, a standard health bar absolutely ruins this game for me. My favorite characters, Nathan Drake for instance, have some of the hardest to land supers and that makes them more or less useless for actually winning matches, and completely negates how well you play during the rest of the match because I have to waste 4+ supers to get lucky and land one. Like seriously, if I'm playing Drake and absolutely owning the other person, barely getting hit myself and building up tons of level one supers but missing with them every time because they are almost impossible to hit with (he tosses a propane can that you have to time to be very close to the person and then shoot it) and then the other person is playing Dante and builds up one level 1 super and hits with it easily because it's just a simple, "make sure the other player is directly in front of you" type thing, then it's NOT A GOOD FIGHTING GAME. Period. I should be the one who won that match, as I was dominating throughout. Wtf.
The matches I play with my gf wind up being an hour long affair because neither of us can get a freaking kill unless one of us picks a character with a cheap, easy to land super and the other one doesn't, but we both enjoy characters with shit supers. If they were going to rip off smash bros, they should've went all the the way and put in the percentage/knockback system as well, or went with a more traditional health bar like every other fighting game. Such a shame, as I actually really enjoy the way it plays and I think the characters are more differentiated than each other with their move-sets than smash bros, but the win condition is a poorly thought out piece of garbage and whoever thought of it needs to be demoted to a position where they can't make key decisions like that anymore.
All that being said, I could see how this game would work better as a four-player party game as opposed to the way I play smash (and by extension this), which is 1v1 on final destination with no items. It's probably easier to land those stupid supers when there's more players on screen, and people aren't paying sole attention to you, but that's just not how I want to play a game like this. I don't usually have three other people with which to play, I have one person, and I want to play a fair 1v1 fighting game. Even if that's not what the creators had in mind it frustrates me that they didn't even include the option. In brawl you can turn off final smashes entirely. That game knew what it was doing.
