Purchased for  the Oculus quest, as we were looking for a fun 2 player co-op to mess with and both enjoy PC flight sims (IL-2 in VR etc). 
For the price, we were not expecting much, and so we have been blown away by just how fun this is, especially in Simulator mode. 
Everything about this is so impressive for such a budget indie game, and I am now certainly going to be buying for PC VR to use HOTAS. 
My only very minor con for this game is that I wish you could take off and fly from the airfield to the engagement point, and then return to the airfield. (And vice versa). The odd fade out and back in when you take off to where the mission starts is not too annoying, but would love to just fly for a few minutes to the battle. 
Anyway a solid 9/10 for the enjoyment factor! :)
