Fairly good
This guide to GoF2 is pretty good, but there are some pretty glaring imperfections. For example, several of the tables on the "Equipment" page are populated with data regarding cabins rather than the appropriate piece of equipment. Also, several items/ships/etc are in-game but missing from this guide. Even with these issues, though, this is still worth it to people who enjoy GoF2. Worth the money, in my opinion.
