In my experience, this game doesn't crash and freeze as much as other Beth games. A lot of things do seem to bug out fairly often though, about as much or possibly more than other Beth games. Regardless, I don't see why that has to be the main point of contention against this save feature. The main thing against it for me is it doesn't add anything gameplay wise except make saving a chore, which depending on where you are on the map or a particular dungeon and how much progress you made since your last save might be anything from not that big of a deal to pretty tedious. I guess I am one of these "casuals" that people keep mentioning.
Having said that, could someone please explain what a "casual" is, because I've played Fallout games inside and out until I'm literally sick of them for thousands of hours, then modded them, then spent time editing my mods so they present an actual challenge while not being overly annoying till I get them perfectly how I want them and seamless from the vanilla game, then I put the games aside for a few months until I remember how much fun I've had playing them. Thousands of hours overall, and a solid month-long chunk or more of hours on FO4 alone, bought the CE, bought the season pass, spent hundreds on merchandise between the FO4 announcement and now and will definitely spend more, buy games on multiple platforms, buy DLC as it comes out AND the GOTY editions, bought games I've had installed on my computer for years just because it came in a plastic shell that looked like a bomb... Plus because I played Fallout 3, I later got wrapped up in TES just because they were made by the same studio and it scratched an itch during my Fallout downtime. I put my time in and I spent a good deal of money to boot, so if someone called me a "casual" to my face, they'd get body checked. And there are many others on here who have logged the same or more time and who are just as into the games that probably would have at least some choice words for people throwing around the word "casual" were it not for forum restrictions. Bethesda does keep their ear to the ground and are receptive to what people want, and a fair amount of those things actually do make it into the games, so if you're feeling stifled by hard heads around here just keep speaking your minds, because enough people saying the same thing will at least cause the devs to pause for consideration.
