The IL-2 Great Battles Series by 1CGS (aka IL2 BOX). This is a niche market, so I am providing additional info in case you are unfamiliar with it. The series has already implemented support for existing VR. The series is one game with separate unlocks for the following:
IL-2 Sturmovik fully released WWII combat flight sim modules with 34 aircraft in total:
Battle of Stalingrad
Battle of Moscow
Battle of Kuban
Battle of Bodenplatte (eventual 10 WWII aircraft - combat flight sim module)
Flying Circus – Volume I (eventual 10 WWI aircraft - combat flight sim module)
Tank Crew (eventual 10 WWII tanks - tank sim module)
The above include large scaled high detailed historic maps of each area for various seasons of the year and varying weather conditions.
Additional modules are anticipated.
