yeah if anything FC5 is more a game that tries to piss nobody off like most Ubisoft games. I never heard of SJWs being mad at it (i know, they are mad at everything) but I'm sure there are a bunch of right wing people also mad at the game for the way it makes rednecks look like retards. Every time the game shows one char with a crazy view ("guns are better than sex!") it immediately side steps the whole thing by having a character next to that person say the exact opposite thing, its totally a design-by-committee kind of game.
Every far cry game is completely seperate from the other and you don't need to play any to play a different one. FC1 and 2 are one set of games ("real"istic) and FC3-5, Primal, and Blood Dragon are a different kind (more whacky). FC5 is probably the best far cry, maybe FC3 is a little more interesting/focused. Nice thing is if you get FC5 + season pass on console you will get a free digital copy of FC3 in a bit over a month. On the other hand its a Ubisoft game, in 2-3 months this game will be like 60% off. If you play mostly on PC I don't think they are remastering FC3 on it, since it'll be pretty much the same game.
I don't think there is really any immediate need to play this game asap, its not bad but its not the pinnacle of gaming or anything and it gets pretty repetitive pretty fast. If you just fly through the main campaign though you can be done in 20-30 hours which isn't too bad. If you start working on doing every side quest and prepper stash etc it'll take 2-4x that time.
I'll probably wait for a sale then. I think one of my biggest problems with these types of games, is how long they are and how much stuff there is to do. I like FPS's with about an 8-12 hour tight campaign. But I get in a game like this, and then I feel like I HAVE to do all this side stuff or I'll be missing out on a lot of content. It drives the completionist in me nuts. So then I put the main story on hold to do all these side quests, which usually burns me out and I put the game down and never come back. Happens to me in all of these types of games, Assassin's Creeds, Skyrim, Fallout, Witcher 3, Watch Dogs, etc. I think part of what intrigues me so far on the stuff I've watched of this game, is it seems more story-led or focused, rather than just a ton of collecting bear asses, but that could also just be the videos focusing on the story content, not the filler. Maybe the side-quests are main story quality, I dunno. When games have side-quests with actual storylines, I can handle them much better. Like Destiny 2, FFXV, Witcher 3, and those types of side-quests are a lot more tolerable.
As far as the whole SJW stuff, if you just search youtube for Far Cry 5 SJW, there's a lot of videos making fun of the SJW criticism against this game, and the videos the SJW's made are about 90% disliked. From what I've watched, it seems most "conservative" people think the game is funny and laugh at the parody of it all. But it looks like there are a lot of SJW's though that are offended or bothered by the setting and people, and the fact that you have to side with some of the rednecks. One of them apparently says "Obama loving libtards" and some took offense to that. Ubi could have played it safe, and made all the rednecks the bad guys or left some of that stuff out, but they didn't, and I appreciate that. To me, controversy and pushing boundries in games is fun. Just look at GTA. That's part of why this game appeals to me, it doesn't leave out possibly offensive things (due to today's politics) just for the sake of not offending people. I want games to continue to be like this, which is why I want to support that. Make a fun game how you want, even if it offends people. Puritans wanted to shut down GTA back in the day, and SJW Puritans want to censor everything offensive (to them) now days. Fuck em.
Here is one good example of how Gamespot had issue with it. Their original video got destroyed on in their comments and like ratio.
