Both the player and the AI? So if someone were to do a one on one exhibition match, one could play as a custom character and go against an AI custom character? I'm pretty sure this is what you are saying, but I just want to be crystal clear before I start to grind for more records. :)
@Megamatt79, yes, I totally forgot about that menu! Sorry, it's been a few years.
So looking at the stats for some of the top superstars, it's clear that custom characters, as a whole, are going to be stronger than most (if not all) base characters. It seems that only the top tier superstars have all 15 stat points to spend in offensive or defensive ability (although even Steve Austin has all 15 offensive points and only 13 defensive points).
This, combined with choosing moves, means that once custom characters are allowed, custom characters become nearly must-use to be competitive. In my humble opinion, this isn't a bad thing though as @Pottsie91 said it just becomes a way for us to tweak things to our liking and add depth to how we do things. However, I can understand if more purist speedrunners dislike the concept because it's not an original character, even though I feel like they would still end up using only a handful of wrestlers themselves anyways.
In the end, I don't feel that I have too much say in a community that I'm newer in and in a game I haven't even uploaded any times yet, but my vote would be to allow custom characters, simply because it allows us to pick and choose different abilities, moves, and strategies in order to optimize our runs, and it's fair because anyone can choose to build a character however they would like. Plus, it's more fun...and that's what we are here for, right?
I'm looking into throwing some times on the boards, and this was a question that I had and came here for. My only question is do wrestlers have different stats? Strength, speed, etc.? I don't think that they do, and if that is the case, I don't see why a custom character would be disallowed. Sure, you can pick and choose different moves, but then again, so can ANYONE running the game, so I would lean towards allowing it.
And if this is the case, I will probably create myself before I come for some of these records. LOL
