I hope posting about other games is fine here. I'm not the dev or anything, just someone who likes OpenTTD and stumbled across Distributrains.
Distributrains is a clearly OpenTTD-inspired game that adds roguelike elements, which effectively means that every X minutes you need to export a specific good (or grow a town) or you'll fail. It's missing some complexities of OpenTTD, but it does require you to acquire the resources to build and fuel your trains. This caused my first coop run to end as a result of failing to pay attention to our fuel usage (and not proactively setting up a fuel production line). I'm excited to play more of it and I suspect it will appeal to many OpenTTD fans as well. The timed objectives and more limited resources are a nice change of pace.
