Bought it from GDW in 1982 or so, but had no idea how to play (I love games, but I am really bad at them. Figured a role playing game - you don't lose!. Okay, you can die, but still...)
Took it with me to college, and found a gaming group and a guy down the hall from me that played. So we started playing. Traveller nights we'd play from 6 or so to about 10pm, then move from the school building (got kicked out) to one of the guys apartments. Play until 2 or 3am, make a donut run (the nearby bakery started baking at 2am for later, and they opened their back door. Donuts fresh out of the oil - no need to chew as they melted in your mouth. Needless to say between that time of day and the sugar rush, games got...interesting). Cool thing was we swapped refereeing and playing between 2 of us, so there was always a chance to play. And it was a shared universe.
In fact - I found my 30+ year old maps and I am reworking them via TravellerMap and a few other things. So there may be more world write ups! Fun thing this was an earlier version of Traveller as the UWP is in the A-123456-C format on my typed up pages (had my dad's old manual typewriter...I must have spent more time making up my own universe than studying for a while. Then I discovered girls [yes, I was a very late bloomer!] and pretty much stopped playing for, oh, 30 years or so. Found this site, found a local gaming club, and actually refereed a mini-campaign for about 6 months as per various links in my sig and files in the files section)Will hopefully be starting a new game sometime in the next few months, bring in some fresh blood.
