Yeah, I never played any of the previous iterations, but I picked this one up, and absolutely hated it. It wasn't just because of the awful server connections... the entire gameplay just didn't appeal to me.
The control scheme was the most ridiculous thing I have ever seen for a shooter. Up/Down on D-Pad to zoom in/out? I don't know how many times I died because I didn't zoom out. I'm too used to having Zoom be one button and when you let go, it un-zooms automatically. Triangle for crouch/prone? Square for Jump? R2 for sprint? All the controls were just plain wrong, and even though you can edit them, they don't let you change the most important ones like Prone/Crouch or the zoom in/out to what a good shooter should be.
Then there is the fact that grenades don't throw worth crap, the C4 is not remote and only a 3 second timed device, the sensitivity when not scoped is way too high, but if you zoom in to try and aim more precisely, the sensitivity is way too low.
All that and the bad servers caused me to return the game within 4 hours. I will never play a SOCOM game again in my life. Maybe that is the control scheme for those games, and if that is the case, it will never be my type of shooter. I was expecting something similar to GRAW or Splinter Cell type controls... but I was sadly mistaken
