Looks real nice, except for one problem- it's commercial paid software.
Paid commercial for-profit software will never generate as much as a community as a non-profit volunteer effort such as BVE.
I have to disagree. The Trainz franchise is a commercial-paid software, and my team and I have made dozens of pieces of content for the game in the last few months. Plus, the community is a lot larger than the BVE community. Aldo, City Bus Simulator is commercial, and Randy is having a field day making custom buses for it.
It just goes to show that no one can enjoy anything anymore without willing to spend a few extra dollars on it. I will not be getting it, of course, because I don't have any interest in bus simulators.
I also like that this game is moddable, as well; it may not have bus routes for NYCTA, but with a few willing developers that can easily change.
