Includes the first two games of the great Tex Murphy series, Mean Streets and Martian Memorandum. Mean Streets was originally meant to be a sort of flight simulator with adventure-game elements to it. The flight sim is the weakest part of the game and frustrating, but the story is pretty good.
Martian Memorandum is my favorite Tex game. Chris Jones and co. clearly understood what worked and what didn't with Mean Streets, so Martian Memorandum takes the form of a straight-up point-and-click adventure. It's my favorite point-and-click ever. The cheesy FMV and voices were revolutionary for their time (pre-7th Guest and Myst). Plus, the Tex Murphy games were the only really good post-nuclear computer/video games around until Final Fantasy VI came out for SNES in 1994.
