Hmm, I've been thinking about this a little more...

When I first heard of Dovetail Games I thought they were making a new simulator. Turns out it was FSX.
I was told they had another game called Railworks which I happened to go and check out. After reading their forums most were leaving the game due to heavily overpriced DLC, think $20 USD for a reskin!  :o

I think what might be going on here is they are trying to capture existing users by charging a pittance for the base game. Then let the DLC roll in. My fear is that they will tie-up with certain developers and that will be it, then they can charge what they like whilst screwing the developers. They have the form and it's all in the railworks forum if you care to read.

I'm not saying don't get it, just be aware of what might happen down the track.

You want to change your livery from Delta to United...That'll be 20 buckaroos thanks....  :(
