I consider 2 the dumpster fire of all Far Cry games.
FC2 had it's share of shortcomings and questionable designs, but I'm with Kerosene31, I think it was ahead of it's time. It had some survival-esque elements before survival games were a thing, and while not every system the game had was executed as well as it could've been, I enjoyed it quite a bit even back then. Honestly wish they'd try their hand again at some of the mechanics they abandoned due to poor reception at the time. I thought the weapon jamming was actually kind of an interesting way to throw a wrench into the middle of a player's plan, they just needed to implement a more intuitive and less frustrating way of preventing jams to begin with.
