there was a era when the most fun of a game was made..then they become overcomplicated with graphics game play ..its why you see pool is still pool..rts hit the most fun with war2 fps is not doom though..fps hit the most fun with doom engine clones..doom 3 sucks doom2016 that otehr doom will not ever be as good as the doom engines for doom.
sc1 boring as fuck game and so every rts after as far as im concerned
all you got to do is go play starcraft muz and come back with your findings..if they are different from mine you are wrong im sorry
honorable mention for fps is q3/qL as the best fps
