Train Fever is a fantastic prototype of a game. I wouldn’t exactly call it “finished”, or even close to that. I find that more often than necessary, I don’t play the game but fight against the game’s various odd design decisions, missing features, and general quirks. There is a lot to be done yet. Granted, the basic stuff is there and works – with the exception of the industry part, which could be fleshed out a lot more. But in most areas, the game stops at laying the groundwork, and misses the refinement.
That may sound more negative than needs be, but that talk about a TF2 has me worried quite a bit. The team behind the game is tiny, so I doubt that working on two titles at once will be possible. I’m quite willing to forgive the current unfinished state of the game if I can expect that it will be worked on and improved substantially during the next months.
Now, stating that “we’re considering a sequel” and actually starting working on one, are two entirely different things. Let’s see what the plans are.
