You can argue that the GR aren't the best pilots to give a review.
And you are probably right, nevertheless they are very popular on yt, and make entertaining videos. I had 2 friends that I have been asking to join me in DCS for 5 years now, but they where like "no its to difficult, no time,.. etc".
Well half a year ago they both started watching GR vids to my amazement and telling me how cool it looks, lolz. This Christmas they actually started buying modules. So yeah, thanks GR I may have found a Rio after all.
So at least I hope HB change their minds and at least give them a copy on release. I think they deserve this!
