If TK wants to sell more SF2, he needs to introduce a "disruption" and VR MAY (I am not even sure of it) be it.
If he does not invest, then the number of player will decrease slowly and SF2 will die, and this si likely what will happen.
Going "open Source" may slow down the phenomenon, but I am not sure it will increase significantly the number of players.
I will keep my old install ... and continue playing it for quite a longtime, but like everybody, I wish it can improve and more people discover this hidden gem.
There is some room for a middle core jet era fighter simulation, but SF2 is not up to date for this.
Would need better nicer terrain, VR and multiplayer (if we compare to heliborne, for instance).
The rest is ok, I think.
