I think the developers are making the right decision regarding the priorities: first get the game playable on all intended hardware, fix all major game breaking bugs (crashes,….) and put together a decent manual (though I would have hoped for a detailed user guide, explaining all about the workings of simulation model, the pathfinding systems and construction restrictions with tips and examples)
I find the list of coming features also quite decent. Especially the waypoints, laying road over rail, and industry chains. Achievements and eye-candy stuff are not my personal priority though.
I’m still enjoying the game a lot, by setting up my own goals with every new game (eg survive on hard mode with trains (done), integrated railway network to all cities on large map (current), grow the biggest city I possibly can (next), …
There will be a day I will get bored by playing the same game over and over, but I don’t blame the game. It’s a great game! And I have all confidence that it will get even better soon.
