Sometimes nostalgia can cloud your judgment. This is especially true for games that sometimes don't age well or aren't adaptable to things like new mechanics.

This seems to be the case for Call of Duty players when it comes to classic maps. Modern Warfare 3 released late last year with 16 maps from the original Modern Warfare 2 from 2009, and players are apparently done with them.
In a June 17 Reddit thread, MW3 players discussed how times have changed, how the games have changed, and how the maps, while largely the same, aren't as great as they were 15 years ago.
"After putting a fair amount of time into MP this year, I can definitively say that the nostalgia for the OG MW2 maps is gone," the thread creator said. "Outside of a few, I don't like most of the maps I used to like."
