I played this game for years, from late in high school through to my mid-20's. It was the inevitable follow-on from Robotech. With more toys in each and every supplement, it's little surprise that this appealed to the style of play I had at the time. I was a munchkin in a munchkin game.
2. Car Wars
A friend introduced this one to me in 1989 and I still have the rulebooks he eventually sold to me. This was a great little strategy game, with crunchy design and - on a good day - a mountain of dice to roll. Somehow it managed to capture the whole process from designing and building a car, through to the huge explosion that destroyed it.
It was the precursor to #1, Rifts. We played it a lot through high school.
4. Marvel Super Heroes
I can't remember how it happened, but we managed to get our hands on this little gem. I've not seen it since, but I think it gets the awe it deserves.
5. Advanced D&D
My first RPG system. My magic-user died horribly in the first game I ever played, and even though I was distraught, I was also hooked. Since then I've spent countless hours at gaming shops and at home, just leafing through game books. And no, I haven't yet tried D&D 4e.
This was a board game by TSR, although I think we had the Jedko print of it. Nevertheless, it was a great little game that we played for hours, over and over again. It was also the game of gloating and being a sore winner or loser. Sigh! Happily, we now have Munchkin to make fun of the whole experience.
More fun that Monopoly, this was another way for my older brother to trounce me. Still, eventually I figured it out and made it tough for him. We had the John Sands red box (to steal that phrase), complete with little kangaroos. It's interesting to see how much the world has changed since this game was printed. Most of the companies on the board don't exist any more.
8. Spirit of the Century
It's slowly catching up with the others, and although it's a contemporary favourite, it hasn't had the hours it deserves.
9. Don't Rest Your Head
I hate this game, but it's a favourite in certain family circles.
