crb? never heard of it up until now o.o

The Core Rules Book.

I designed UF (User Friendly) to be seperate from most other RPG's; it's already a stand-alone, complete product without any other books (unlike DnD, where you need to buy a minimum of three books to be completely effective as DM).

The Core Rules Book is all the basic stuff and base rules; everything else in the other books does nothing but add upon what's already there.

so this is like your own little RPG style game?

Yeah. I started it back in 2000, went through three different systems, and finally finished it earlier this year.
