That's exactly why I would give them a Mig-29. :lol:
It is recognizable but nowhere near as appealing to western ( the majority?) market as the US teen series. Bait them with a cool looking fast jet to give them a taste, than sell them what they really want.
Su-25T doesn't really scream " Highway to the Danger Zone" to casual gamers, Mig-29 would.
Interest for flight games is there, just look at how War Thunder is thriving.
But you need to appeal to casual gamers.
