Good for you mate. As long as the visuals aren't literally all over the place, gameplay really is king.
Take Project Cars for example (or not in your case

), the visuals certainly don't match DriveClub. But the action is fast and frantic and you really do think the graphics are amazing when flying around the track. If you watch someone else play and concentrate on the scenery rather than his driving, the visual niggles will come to the fore. Horde mode shooters (even more so than racers) get so frenetic as you progress, that the immersion is sustained. The aliasing isn't really that noticeable.
In RPG's or open world titles, it's easy to pick fault whilst ambling around at low pace studying the vistas. Take TLOU on PS3 (and to a lesser extent on the PS4). If you want to ignore the detail and critique the aliasing it's easy to do. But that's not the whole package. It's telling that the Witcher 3 got picked out on it's visuals (grass etc.) when the world they have created looks so fantastic. I never bemoaned the huge frame rate hit on the dead end gantry in De Reise, at level 35 when there were four players being over run by 50 zombies.
Glad you're enjoying it mate, but I won't be getting an Xbox 360. All my spare cash is going toward my build. Then I'll be downloading Killing Floor 2.
