the Quake 2 remaster and how much i enjoyed it i feel at least partially correlates with how much bullshit i was willing to put up with and how much i'll go to bat for Red Faction, which i played first and still adore.
this being said if you enjoy either of these games and haven't played the other, i think you'll like it a lot.
if you are planning on playing Quake 2 just play the remaster
if you are planning on playing Red Faction please for all that's holy install Dash Faction:
i think Red Faction really shines in those set piece moments like when you first manage to break into the guard's training area and a stationary grenade launcher is sitting there in middle of a concrete room with little slivers of cover. when you mount the turret it purposely spawns in a bunch of guards that flood in from both sides of the room, allowing you to go ham just fragging dudes left and right, also this track plays.
