Larry 7 was great! It's called Love for Sail and it takes place on a cruise ship. I thought LSL 6 was good too, although not quite up there with LSL 2, which was fantastic.
The best part may be the Chinese "Spork" vendor who was raised by Irish missionaries.
I didn't bother with Magna **** Laude, because Al Lowe was not involved. And if he's not writing it, it's not a true Larry game.
Anyway, Wolfenstein 3D was my first game. I played the Larrys too, but my first RPG was KOTOR, ha.
