This game is really really enjoyable if you enjoy making things work. Starting off by doing the few missions that are there to make you get a feel for the games mechanics, and then progressing to freeplay, where the real game is, it kept me busy for a few hundred hours already. And i get distracted pretty easily. The only bad part would be that I kind of forget to eat, drink and kiss my wife, as there is always some optimizing to do, some railroad to build before a field of iron runs out or some power thirsty equiptment to feed. Other people probably will write more usefull reviews, but if you want my opinion on this: If you like games that are a nice challenge because they make you think, go here. I really really like it.
