Before casting stones at Marc for the survey, how about everyone ask themselves this question.
How many games have I personally designed while also living my life?
I have designed one, edited a couple, and modified a lot. Yes, Traveller 5.10 will likely not satisfy everyone, but that is the nature of the game. Marc's doing all of this himself, and that is not easy to do. I am having a hard enough time finding time to work on stuff for my version of Cepheus Engine, and make sure that any supplement also works with Traveller. Marc and I are in the same age bracket, so how about cutting him some slack and back off on the negative comments?
