I use several of them. I found the unmoded game fun but tiring pretty fast. The only reason I purchased IV was to play LCPDFR. Now I have changed the cars, lights, added several enhancements like the spot light and plate scanner, The policing script, ELS, Tow Service exc exc. I am told a lot of mods cause problems but I have yet to see a stability difference between what I have now and before I added anything. I do read that MP will cause problems unless the players have the same mods meaning chances are I will never get anyone to play MP with me unless I get rid of some HAHA
