I know some people pirate software simply because 30 days isnt enough to test certain things. I'll have to admit (and I was under 18 when I did it, and I dont do it anymore, and obviously I bought it) I did it with 3dgs. I had a cracked a6.31 pro version, I didnt use any pro features, but tested all the comm. features until I thought I was decent enough with it to know that it was something to could do and would meet my needs.
