What happens if i buy a texture set with real $$ and then u guys update toribash and i have to buy a whole nother set do i get a set free or do i have to buy another set

Don't worry, even if you have a texture set and Toribash gets updated, you can still use the texture set you bought.

This hasn't happened ever in the past, and I'm sure that it won't happen in the future, either.

So, just don't worry ;)

ok thats good
