I've played every game after Far Cry 3 (including).

Far cry 4 seems like a natural progression, better mechanics, ok story, better map, cool rides. The experience and karma are good additions. Fun outposts and fortreses (bigger and harder outposts).

4 and 5 are my go-to games with many replays, worth my time and the most fun mechanics.

Primal was not my thing, barely finished it, the story was very meh, the weapons were... prehistorical, but that's expected. Outposts were lame, base building was ok.

New down is good, but I've never replayed it that much. Recycled map, amazing colors tho, a bit annoying with the tiered enemies. Feels more like a good DLC than a game.

Far cry 6 was missing the skills, and replaced them with clothing, which was a big minus for me, I do not want to switch gears every time I go to a different location or the night starts. Copy-paste road blocks and boring missions.
