OpenTTD 1.10
IMHO the annoying thing with (Open)TTD is the economics model.In the beginning it can be a bit though, but once you get over the initial hump you're more or less swimming in money for the rest of the game.Secondly, it's annoying how small trains become uncompetitive later on in the game. Yes, you'll have much smaller number of these megaroutes bringing in the megabucks, but you have plenty of formerly cash flow positive routes that simply can no longer cover their running costs. Yeah, maybe that mirrors reality with rail transit, but dammit, I want to play with trains not run trucks and buses.
