I never got into 2300 in the old days, since it was a totally different game than Traveller mechanically and flavor wise. Obviously, now its a variant of Mongoose Traveller. I still haven't bought anything for 2300. What do people think, are there 2300 books that make good resources for regular Traveller? Like maybe Tools for Frontier Living and Vehicles of the Frontier? Or is the setting just not compatible even with a common ruleset?
