The intended grf will be fully usable by ttdpatch, however. More than three years ago I wrote the Openttd Challenge Spinoff (OCS). It added a different gameplay goal to the game, other than making lots of money or getting your company rating up. It was a spinoff because the code changes were terribly invasive and a lot was hardcoded, which meant it was impossible to include in the main trunk. Fun was had, but it was of a temporary nature, because all the pretty new features in the trunk could not be added to the spinoff.
Fastforward to about half a year ago and peter1138 noticed that with a number of key functions added, implementing the OCS gameplay became much less work. So much less so infact, that it just might be possible to create it as a proper patch setting.
Skip to the present, and we're at the point where it's worth the effort of seeing how feasible it is. To work on this, we need a grf that implements the industry chain from OCS. The details can be found here. Other information about what this is all about and how this grf will be used is also on that page.
Is there anyone willing to build this grf for us and speed along the development of a different game goal? Full credits will be given, ofcourse.
No mineral exhaustion or stockpiling mechanic is required, no new graphics either, just reuse of the existing graphics. No special ottd features need be supported, it can be coded as a ttdpatch industry grf (this is afaik, I might be wrong). I'll be glad to answer any other questions.
