I was thinking that it would be great to have a big epic ADRIFT-game on Steam. Steam is the place where most PC gamers get their games. Steam has 90 million active users and 60% use Windows 10. Sales are known to go significantly up when indie-developers put their games on Steam compared to selling their game on other platforms. The same is the case with the number of downloads if the game is for free.
I know 2d point-and-click adventures are not comparable 1 to 1 but the free game “Heroine's Quest” which was made with Adventure Game Studio (AGS first released in 1997) has more than 500.000 downloads on steam but “only” 38000 on the AGS website where people normally download those games. So more than 10 times more than their normal website.
I am sure a significant fraction of the 90 million active users might have played text adventures when they were younger, but they might be unaware of the thriving IF community. So when they see a “modern” text adventure on Steam they might get curious and buy/try it and get hooked. By modern I mean a bit of graphics and music and then there is the auto-map, which many IF gamers outside the ADRIFT community have praised. If a lot of Steam users began to play ADRIFT games it would be good for ADRIFT.
So I was thinking that maybe the ADRIFT community (those interested) could work together on a game. I wouldn't mind if I e.g. only beta-tested the game or if I had made significant parts of the game, as long as the game succeeds. What is important is that it is a quality game with significant testing and bugfixing. As an example I think both The0didactus's Skybreak! and most of Lazzah's larger games have commercial quality apart from a few bugs and perhaps the layout could be improved a bit. A game like Skybreak! is very different from e.g. Lazzah's more traditional games, but if those interested cannot agree on the type of game, we could make two games

I don't know what is best, whether it should be a free game or if it should cost a few dollars. If it costs something, Steam might promote it more, since they get about 30% of the sales.
Some things I think is important (probably more to come):
1. It shouldn't be part of a series, since players would prefer to play “chapter 1” first
2. No Copyright issues
3. It should have a decent cover art
4. Nice music (e.g. Eric Matyas has made over 2000 tracks for free)
5. Significant testing and bugfixing, lazy coding should be avoided
6. The game is released as an .exe-file and not a taf or blorb.
7. Those interested should agree early on attribution and earnings
8. Everyone who contributed should be mentioned in the game, if nothing else then as a beta-tester.
I personally don't care about who gets the money and it probably won't be much anyway. I am mainly thinking about promoting ADRIFT significantly.
Would anyone be interested in collaborating on a game like this?
Any thoughts?
