Matter of fact, I just played TM Monopoly twice in the last couple of plays, followed by my current play of a new angle of attack on Blackhawk's beta North vs South. I am approaching this with a far different strategy this time. This map is a 80-100 year map with many events that is playable with two minor edits to remove two events which yield a game loss but are firing for wrong reasons. I PMed Blackhawk about it awhile ago, but if you want to play it I can tell you what to do or provide a temporarily fixed copy (leave the more subjective things that don't break the game to BH). What I am doing different this time: focusing on passengers more at the start. Planning to make most trains express-only mid-game with dedicated freights.
I think TM is a finished product as far as crashes and bugs go. There are some small things that could be considered small design overlooks to do with some of the supply/demand chains such as demands too small to attract cargo well, some industry loopholes, and things like the Tavern that goes crazy when gambling, but I would think of it as a patch if those things were fixed, 95% of the game is great. What it needs is more maps to make mastering it more worthwhile. I have tried to start on one myself, but find myself preferring playing than working on it.
I do agree that comments here seem to be to yourself, but non-members surely stop by to read? Maybe why I haven't posted that many. What would you like to discuss?
