I still remember how the books smelled fresh out of the box. It was unique!
Megatraveller was, at the time, a breath of fresh air that pulled everything together into one place with one unified system. I enjoyed the vehicle design system as its own mini-game, I spent a lot of time looking around my neighborhood and designing every vehicle I saw. I was the GM and the only one with the rules. I backported the whole Rebellion setting to our quasi-Spinward Marches campaign and used the chaos to stage a Vargr invasion. Good times...
