And Out of This World (or Another World...), which is one of my favorite games of all time!
I couldn't get Battle Chess to work. It kept giving me a memory error. I even read the readme file that says how to fix it but the option it mentions isn't available in the Controls pane for Memory. :(
Marathon Infinity is what I was excited to see in there. Runs well too! I can't say how many hours I spent between the base game and Anvil.
"See you starside."
Frog blast the vent core!
I spent so many hours messing around with Forge
Always wanted a proper 3D remake of Marathon - Halo didn't really scratch the same itch
