The original CoD4 is good rather than the MWR. I could explain simply not by including some controversial things like microtransactions. Graphically wise, it is easier to spot enemies on the original mw1. MWR is much more realistic in which darkness and smoke block view that is pretty much 5 feet in front of you. Because of this, it may add emersion to a game however replayability is lower. The other thing is connection in mw1 vs MWR is practically night and day. Originally, youd connect to people with connections around your speed. Itll be somewhere around 25-50ms. MWR is somewhere around 75-100ms because you're not on VPM, Higher end cable, nor buying microtransactions. Something as simple as this destroys playability.
