Hello, I don't know if there is any release of Gears of war 2 & 3 for PC or not(I found that it has not been released for PC)

. Is it possible to run it in PC via any emulator? if yes please anybody can rip & compress the same?
Here in below link they told that the game can be played by the given Emulator

, but again the size is very big

, so there might be possible to compress the size?
