In point graphics a lot has changed. One notices the title just the two years that lie between the 3rd and 4th part. Not only the graphics are converted wunderhübsch but generally the environment and the level design is truly implemented fabulous. At every corner there are all busy, regardless of whether you are attacked by an animal or special Charma events occur. The world of Far Cry 4 is so full of life that the game exudes a very strong and dense atmosphere. However, every now and then come some unwanted AI problems to light. Such as the fact that about every 5 minutes, people in Kyrat be attacked by crazed eagles swoop. This eagle grab even pigs in the wild. This goes so far that you as a player has the feeling that Kyrat being bullied not by Pagan Min, but of eagles.
Apropo: Pagan Min is the new villain in Far Cry 4, which is actually set from the first until the last minute very great scene. You can tell the character, how much love, the developers have put in him to let him act as he indicated in that game actually does. The villains of the 3rd part, Vaas and Hoyt, of course, are also very great staged characters. Pagan Min can maintain the level of these persons in any case. Definitely. In general, the characters of the 4th part are definitely succeeded.
Finally, I would say that Far Cry is 4 big brother of Far Cry 3, in almost all respects. Whether graphics, scale, atmosphere, Arsenal etc. But at one point the predecessor nose slightly ahead: The Story. It is the 3rd part noticeably deeper and more mysterious, than the successor. This does not mean that the story is bad, but that the story of the 3rd part in some places simply accesses deeper into the matter and generally has a greater backstory. All in all, however, is the new part of the old in every way!
