VirtualBus is a free bus simulator, created by a community of enthusiasts. Drive a bus around a city route, picking up and dropping off passengers!
The developers say that, 'there aren't cool graphics, and reality isn't so great,' which is a good description of VirtualBus! Buses and towns are modeled by the community, and while the work involved is impressive, it looks basic by today's standards. There are complex and comprehensive keyboard controls, allowing you to do everything from changing gear and steering, to opening the doors and tilting the bus for passengers.
VirtualBus is definitely only for Bus enthusiasts. The 3D environments are so basic you can actually drive straight through anything, be it a building or a hill! Vehicle handling is uncomplicated, and driving a bus is surprisingly easy in VirtualBus. The fan community allows for plenty of maps and buses to be imported into the game, but despite this, VirtualBus should be filed under 'nice try'.
Made entirely for free by enthusiasts, VirtualBus is very much an amateur simulation. The graphics are outdated, the physics are as basic as can be and the game can't really be described as fun to play.
