My Duo is October 1992. I ordered both Implode and the regular edition of Meteor Blaster from TZD. I guess I should be OK.
I just pulled my Duo out about a week ago for the first play in about 5 years or so, and I am addicted all over again! The Duo is running great, and I'm loving the old games, trying them all out again. I thought Deep Blue couldn't possibly be as bad as I remembered. I was wrong. I played through Bonk's Adventure last night - didn't defeat King Drool though. What a brilliant game! I'm mad though because I lost Soldier Blade, one of my favorites. Can't find it, but I have the book.
I love the original Asteroids and have not liked any of the other versions I've played, so MB is a no brainer. I love that Mindrec is able to make a game every few years, I have to support the great idea of independant games for such an old system!
