Noteworthy titles: Arma 2, Arma 3, DayZ
The scale the engine can achieve, with accurate ballistics and physics models is outstanding. Bullets penetrate materials realistically and emerge from the other side with re-angled projectories and velocities.
Whilst the engine does have its quirks and slightly odd animation snapping, the engine serves as a reminder of what the PC platform can achieve with engines specifically designed for it. A great simulation engine that pushes for realism in lieu of gameplay, Real Virtuality has the accuracy and power to pull it all off, whilst still allowing for user-generated content/mods to be easy to develop.
