Have genre evolutions ever ruined an old favorite of yours?
I consider Medal of Honor: Allied Assault to be one of the greatest war FPS games ever made. A relic from back when EA still stood for quality. It's got a substantial campaign and that's not even counting the expansions.
The problem is that I just can't seem to get into it anymore. The gameplay just feels so stiff and dated now. I mean, you can't even aim down the sights, and compared to games that came out a few short years after, the enemy AI is pretty dumb.
Are there any classics you have a hard time getting back in to?
