It's really not that complicated once you get familiar with it. I picked up my old tuto + an existing mod with new playable stuff for template, and I've managed to add 2 new playables between monday and now.
It can be surprisingly quick if you have a finished textured model, even taking into account the time needed to arrange the model for SF.
But, that's the problem, I don't want to waste my time creating an umteenth Panzer XX model when there's already a ****load of good existing models in various games. So I ripped some models out of other games or mods, which means personal use only.
