20 characters is plenty when each character is unique and fun
I'd hate to be that guy, but it's missing a few characters to really make it feel like Playstation All-Stars. It's kind of obvious who two of these missing characters are, Crash and Spyro. Once again, I hate to be the guy to say it.
Don't get me wrong, I love the current roster and the characters in it. It's just severely dissapointing to hear that they didn't make it in. It just doesnt feel like Playstation All-Stars completely.. To me it's like if Smash Bros. forgot to add Mario in, or when Megaman wasn't in MvC3... It's just kinda really disappointing to me to hear that 20 is the final roster.
Now if you are bringing up DLC, Crash and Spyro are far too important to be DLC characters and not the launch roster in my opinion.
And that's just your opinion. It's generally agreed that the roster is crap.
Two coles, Big Daddy, characters made with the sole intention of advertising unreleased games...
When you boil it down, it's maybe a 15-16 character roster, with some filler padding to reach 20.
