Somewhere in the heavens…

The Marathon Trilogy has been released for free.
For those of us who've never owned a mac in our lives, this is probably our first chance to finally play one of Bungie's biggest games and what some consider to be the prequels to Halo.
Installation (for Marathon 1, as it's a little more involved than Marathon 2 or Marathon Infinity):
1. Download Aleph One Aleph-One-Windows-20040417.zip (1.21 MB)
2. Download M1A1 (the Aleph One conversion of Marathon 1) m1a1_sdl.zip (37.3 MB)
3. Extract AlephOne-Windows-20040417.zip to the hard drive of your choice.
4. Extract m1a1_sdl.zip to a temporary directory.
5. Open your temp directory, open the M1A1 SDL folder.
6. Move ALL the contents of M1A1 SDL to your AlephOne directory.
7. (optional but recommended) Rename AlephOne directory to Marathon1
8. Run AlephOne.exe and enjoy!
You'll want to goof around with the game's settings. I had to turn the brightness up to full because the game was WAY too dark on my monitor but it might just be me. To install Marathon 2: Durandal or Marathon Infinity, follow the instructions from trilogyrelease.bungie.org.
Edit: Added a little gamma to the image, it was kind of dark. Like Marathon!
