Whew. That was a lot of reading....
Yes PS All Stars is not good, according to reviews.
When compared to SSB, it is terrible -- WE ALL GET THAT.
But why would we compare something Nintendo does excellently to something Sony is just trying out??
I think give it time - if Sony makes a sequel, it could be great!
For now though, it looks like Sony's first foray into this type of game has not panned out. But at least they tried!
I think Sony will continue to try out new ideas and they should be recognized for that (even if is doesn't work out like this particular game).
Vita needs Monster Hunter.
