Wow, I didn't want to believe it, what a waste of time.
First, the way it seems is that Sakurai is going for quality and not quantity with characters. Fine. But the only way I would agree to this ZSamus thing is if there were a lot of other characters.
Second, if he's only making X number of characters, and that number is relatively small, why is he wasting time on a character you will barely ever see? I'm sure if you're lucky you can pull ZSamus out in the first half of the match, again, if you're lucky. Not even considering if you don't get the Final Smash until the last few minutes of the match.
It just doesn't make sense to spend all that time, energy, and resources on a character that, whether the character is the most popular or the least, will be hard to even get to.
"Yay! I get to play with a character for the last 2 minutes of this match! I'm sooooo glad Sakurai spent time on this and not on a character that can actually be used."
For the love of god, give us another way to get to ZSamus.
NOTE: In response to people saying have ZSamus as a separate character, because the separate character slots don't mean separate character, they mean "separate character SELECTION." So, that destroys the "same character BS" theory, any other reasons?
