Traveler: Where do you begin?
Hi Gladiusdei, I've been playing and GMing Traveller since it first hit the shelves.
Looks like you've already begun. The first step is to decide which of the many versions you want to play. The good news with Traveller is that every version is still available, so you have a free choice.
Ask any Traveller player and they'll suggest a different version. Usually the one they started with. I started with Classic, and that's my favourite. It's simple and straightforward. It also meshes with most of the others (since they were all derived from it) so if you are into rule-mining from several versions, it's easy.
Megatraveller and The New Era suffered from rule bloat IMO, but if you're into having a rule for everything, they may suit you.
Traveller 4 was a re-vamp of Classic, and Mongoose was an update of Classic. The current go-to is Mongoose 2Ed, which I haven't read. I have limited experience of Traveller on Rpol, but my impression is that the most popular versions here are Classic and Mongoose.
Ask questions here or Rmail me, where I can put you in touch with further help that I'm not allowed to give here.
