When we move from GTA 3 GTA 4 editions, it takes a little time to get used; everything is more realistic! The campaign will miss some (SA), but soon returns to GTA 5 :) For 20 it worth ... When it came out in 2008, it was considered a greedy game, but now on newer computers it passes very good. The graphics are really great! I recommend, because it is not to be missed, play it before GTA 5;)
