Merits of 1st In vs Space 4e?

lentulus · 05-19-2011, 08:54 AM

I am looking for a good written (PDF format) set of rules for Hard SF system & world creation. I have played traveller in the distant past, but the systems I see most often recommended are both from SJG: Gurps Traveller First In and Gurps Space. I am not running an SF RPG per se, but looking for good generic tools to put together a hard sf universe.

The obvious difference is 1st In is slightly cheaper, but Space looks like it may have more useful secondary material. However, at the core, what differentiates the two world creation system?

Is Gurps Traveller still in the hexadecimal world of traveller as I knew it, or can 1st in be used without the overhead of other books?

Does either of the systems use metric, or are they both US common units?

What other points can I use to guide my choice? I will be buying one or the other in a week, so guidance would be appreciated.
