Steam, Tracks, Trouble & Riddles (S.T.T.&R.) is a single player adventure mod, based on source engine (Orange Box) by Valve. It combines two types of game play: an adventure game with complex, 3D-interactive riddles in a fantastic environment and a simulator for track based vehicles.
There is a survey about the way of release on interlopers.net

Hi friends of Steam, Tracks, Trouble & Riddles
since 2009 I am now working on this mod.
If I will continue with this rate of development
the estimated release date of the whole project
will be in about 5 to 7 years (Valve Time).
But if i would release chapter by chapter,
(there are five chaptersat all)
the release of the first chapter maybe will
come in about 9 to 12 month.
I just started the survey on www.interlopers.net
Thank you for voting!
