That said, Source games as a whole are looking pretty dated at this point. CS:GO wasn't great looking when it was released and other than a few modern touches it's not actually that much better looking than some of the custom CS:S stuff I've seen.
Also if only every 3D game from the early to mid 90s could be cleaned up with new visuals and fitted with modern control sensibilities. So many great ideas now rendered nearly unplayable by awful visuals and controls.
