What I will say is that I have stopped playing all other games and even railroad tycoon 3 is collecting dust since TRS2004 Arrived. I would also like to add that I have a 5 year old son who loves driving/watching the trains go round. I've really enjoyed playing with TRS2004!
It's hard to explain, but playing with TRS2004 is exciting and fun and there's so much to look forward to (I download new things for it all the time)
So Let's review:MS TRAINSIM = BORING = You'll want to go to bed early.TRAINZ RAILROAD SIMULATOR = EXCITING & FUN = You'll want to stay up all night and you just might call in "sick" the next day ;-)
Hope this review helps you in your purchase decision.
For me, fun is what it's all about.
Target market is very broad, the sort of people who are interested in model railways certainly have taken it up. But there are many youngsters 3+ who enjoy watching the game or simulator. The jet engine in this version is new, it takes advantage of the new graphics cards to allow more interesting water effects. It also is more efficient than the old version but that is balanced by the some highly detailed models that need faster computers to run. It also seems to run smoothly on a wider range of video cards than the old version. Auran has upped the minimum suggested requirements but since this version is more efficient some quite positive comments have come from users with less than the recommended systems. The software can be tuned to take best advantage of the hardware and quite detailed instructions are available in the forums on how to do this.
In a word enjoy.
