You'll get more than 51 weeks more of enjoyment. Like anything else, the more you put into something that can take it, the more you'll get out of it. As an owner of previous versions, you should know this.
Like many of the longtime posters here, I've been with Trainz since TRS2004. I too tried the old demo in 2002 and only wished at the time that it would run on my system. I had a PIII with an ATI 8500 in it, and the program would die with either a black screen or crash to the desktop. I stuck with MSTS until TRS2004 came out. It's funny I wasn't looking for any updates in particular for Trainz, I just happened to look at the old, original Auran, website one day when I was cleaning up my favorites. I was excited by the 'new' version that was coming out, and waited to buy TRS2004 at CompUSA.
Now almost 8 years later, and I'm still with the same program, albeit the latest version. I still enjoy the thrill of sitting in the cab and driving or riding the route that I built. As a model railroader, this was something I wanted to do since I was 6 years old. Imagine a program like this back then. That would be in 1967, which is around the time when I got my original N-gauge Postage Stamp train set. As Brian (Kennilworth) said. Perhaps the problem is there's too much for everyone. Trainz isn't all about driving a set of preconfigured, premade routes. If I wanted that, I would have stayed with MSTS then moved on to Railworks. Like a real model railroad, made of plaster and plywood, there is so much that can be done in Trainz, that the only thing stopping someone is their ability and their imagination. You tell me what other program is out there today that even comes close to this. I have more banished programs and games in boxes on my shelves that I purchased, installed, then deleted. Why did I keep the programs and boxes? I really don't know. I felt it maybe I would give the programs a try at another time, but that other time never came. They've been abandoned and kept on the shelf.
Granted, like anything else in our imperfect world, Trainz isn't without its faults and limitations. Like any software we use, we learn those limitations and avoid doing things that don't work. If the developer is kind enough, they will provide us updates that we can replace our faulty versions. I feel too that N3V, like Auran, has tried really hard to provide updates and fixes to our beloved program. We really are pretty lucky to still have them around after the big company crash in 2006 or thereabouts. Like the OP, and many newcomers, they never saw the old company crash after the Fury mess. If it wasn't for TRS2006, and the Classics series, we wouldn't have what we have today. TRS2009 was a transitional product. I'm not sure how many people remember Tony Hilliam say that this is a developer's platform for content creators to learn how to build content using the new methods. TRS2009 lead the way to TRS2010, and finally to what we have today with TS12. TS12 is not perfect. There are still plenty of things that need fixing, and I too hope that there will be a fix some day.
Perhaps the griping we do here is because we love the program so much. This is like the parent or parents that scream and yell at their child because he or she hasn't tried hard enough at whatever they're doing. I agree there's plenty that N3V could do to make things better. Like better and more communications. So, let's hope they do listen to us and make some of those changes we've been asking for.
