YS Flight Simulation System 2000 is the shortest game that can be described as a fully functional aviation simulator. Enables simulation of more than 50 types of fighter planes (e.g. F-15, Mirage 2000, Mig-29), passenger planes (e.g.

Concorde) and helicopters (Apache). Air battles can be conducted either with a computer or with friends over the network. An interesting option is the ability to record your feats in order to improve your skills later on.

The graphics may not be as captivating as in Microsoft's Flight Simulator 2004 ;-) but in the end the game as the only one (or one of the few) of this type is free of charge. This of course applies to the OpenGL mode because in the standard mode it is better not to run it ;-) The fact that the hardware requirements are also low is a consolation. All in all, a lot of fun.
