This always confused me. They shamelessly copied motion controls from Nintendo, so why not shamelessly copy Smash Bros. instead of making this ridiculous gimmick? If they'd just made it "Smash Bros., except with Sony characters" then it probably would've done fairly well.

That's another thing, though, the roster just had a bunch of 3rd party characters. I guess Sony doesn't have enough confidence in their own IPs to push them. I think that'd be a lot more welcomed by Sony fans, personally, but ...

Would be awesome but it is a pipe dream.

Great chance to get to know them then.

Just download MUGEN /s

To be honest, I don't see why it has to be a smash brothers clone. Why can't it be like a traditional fighting game, or even something more similar to power stone? Trying to emulate what smash did is just a very narrow-minded way of looking at things.

woooah ... I just looked up Power Stone. The gameplay and camera angle looks awesome! 

I don't know why there aren't more fighting games with that camera angle. It seems like the perfect kind of template for a Playstation All Stars game : D 

Too many balance issues though

Le problem is there ISN'T many PS or Xbox all stars.
Let's be honest here, how many chatecters from Sony or Microsoft first party can you think of that is say... Higher than Rosalina in terms of relevence on thier console?

As much as I love Smash, obviously as more of a Sony guy I have a hard time getting excited about the characters. At least they have brunched out more to include more 3rd party characters. I'd rather Sony made a new All Stars and actually put more effort in, Sonys first party characters are more diverse imo.

While the idea sounds epic, it wont actually work well on paper. Both Sony and Xbox have very few characters that will actually be recognized. The Balancing of the game will be all over the place and unless they make it cross play on all platforms which we know not all companies want to play nice especially with a game carrying there mascots. It will be a huge mess.

Best thing they can do is that companies like Sony and Xbox can ask Nintendo to put there characters into Nintendo's game as DLC, or Sony and Xbox team up to make a Smash Brothers clone where it will be PS vs Xbox characters and the game is cross play between the two systems.
