mods are like women, we all have different tastes. i find petite women with small breasts attractive and some people prefer tall women with big hooters.
only you know what you like so read about them and the ones that interest you try them all, keep what you like and remove the rest
lots of people set up more then one version of the game to play different groups of mods without all the installing and uninstalling
i would suggest you give the american side of the game a try, it IS the main thing the game was designed around and shouldnt be ignored.
try my GFO mod, it doesnt change the game much and is a great way to improve the stock game. once you get used to the game and feel you are ready for it to be more challenging then try the TMO mod, i think its one of the best mega mods designed to change the game and its very well done
