Creative competition
The next main feature is trainz exchange, where you can exchange content with other users.
As you may or may not know all the routes and some consists in Trainz 2006 are user created, all Auran did was some original content from Trainz ultimate collection and obviously create the game's engine.
I personally am quite suprised at the overall size of the game, and how you get the option of buying it over many CD's or purchasing it as a single DVD. On the cds/DVD you have other applications to do with trainz, such as content manager and content dispacher. You also have trainz paintshed, but I can't seem to be able to work that, as an error screen about an English language pack appears.
Noticably I have the latest video card drivers and DirectX, but the game still has severe lag in a form I have never seen before on any other game. I can't understand what causes the game to lag, It may have been because of the large filesize, but I don't see how as the game actually is compressed into several different JA files, of which cannot be extracted to modify as can be done with some other games. Overall I rate this game 7.5/10.0
