It would be a welcome addition, though they tend to suck (too hard, too easy, or just build plain nonsensical stuff….looking at you Railroads!), but still, I do enjoy the occasional clever AI.
Well. Maybe we could play against the AI with multiple difficulty levels. (easy, normal, hard, expert). But this might take a lot of work for the developers. If it is possible the world comes much more alive as you dont only play against yourself but also other opponents.
We know that this is a wanted feature. Due to the large amount of resources needed for the integration of an AI we’re not releasing Train Fever with AI opponents. It’s planned to work on AI opponents after a successful release.
