A while ago I bought a game called the Moon Project. I just dug it out and it doesn't say Earth 2150 on it. Is it still the standalone expansion for the game or is it a completely different game? It says Topware Interactive and Pier 57 as the developer and publisher.
The only reason I don't just install it is that I only have a netbook and I don't want to go dig out my external DVD drive.

Quote from game's card on GOG.com:
"Earth Trilogy includes Earth 2150 and both expansions The Moon Project and Lost Souls."
;)

O, I see. Sorry for misinterpretation. ;)
I've also heard only about one "The Moon Project" by Techland.

My CD does have the same pictures those boxes except it doesn't say "The sequel to Earth 2150" in the corner. Thats why I was thinking it was a different game. I think I'll probably just buy the Gog version because its cheap and has the other two games with it. Thanks to both, sorry for the confusion Nox.

Funny enough you mention this game. I picked up a complete boxed copy, with the manual and strategy guide, over at Goodwill for like three bucks. I was wondering if Earth 2150 is worth it was since they're pretty much exactly the same.

Only if you like playing the campaign I think.
