I just found out that you can do costume swap mods etc with a non-cracked .exe, as long as you have legit DLC installed (except for the bikini mega-pack).
I have never used the best mods before (because the cracked .exe wont let you play online... and its kinda dodgy) and I didnt want to pay full price for DLC either, but to use those "proper" mods, I think it will be worth it.
I was going to buy the bikini pack, until I heard the costume mod tool wouldnt work with it. Now I think I will buy the pre-order pack. Its the cheapest one, has some nice outfits and was the DLC pack the guy used in his tutorial. Its extra frustrating having to spend 25 USD on outfits I would have gotten for free, if I had enough confidence in TN to pre-order the game :'(
