While I applaud you for the work you've done in such a short time, you really shouldn't be so rude in response to criticism. I checked out the mod, and agree entirely with the points Stennick made.
Playing the game, everything does feel a bit rushed. Almost as if you were forcing yourself to get enough done to release in hope of receiving a few compliments as opposed to putting ensuring things are historically correct. Sure, we're talking over twenty years ago, and you've admitted that you haven't got great knowledge outside of the two main USA promotions, so things aren't going to be perfect.
If I would give you one bit of advice, it'd be simply to ask people on topics you're a little unsure about prior to releasing it. This would give you a stronger grasp on things you're not so sure on, thus avoiding people posting issues with the mod and you taking said comments to heart.
I have fairly strong knowledge of ECW and WWF around this time, so if you need any additional help with those I'd be happy to help. Also with promotions etc that you feel you have very weak knowledge on. I don't mind researching things myself to help you out, as this mod does have potential.
