@freemo Would recommend, its still got a couple problems but I've already managed to lose ~50 hours to it.
If you do get it I would recommend getting a few mods (CopyInserters and AdvancedBuildDestruct) with r2modman. It makes building the large scale factory stuff much less tedious.
@ephyra Thanks, next time I have time for a game (I'm putting what little freetime i have into writing one) I will consider it.
