For the small price of G-Core you get a lot of bang for your buck. I'm an old Marvel Superheroes FASERIP system player and GM, so I was really happy to see DGBG come out with this nice rules-lite system. It really is true that you can convert the old FASERIP characters to G-Core in a couple of minutes. That means all of my old information can be converted over very quickly.
There are a few minor editorial fixes that could go in here but that is a minor gripe. DGBG has been supporting the hell out of this product with add-ons and has been very responsive to customer requests, so if you don't see something there that you'd like to add, give the company a few weeks. :-)
Overall I am very happy with this product.
