I just fired this up recently and couldn't see a whole lot off the top that was different from when I played it last year, other than random starting places, a few new items, and some tweaks here and there. Gameplay still seems to shake out the same way more or less. Spend the first day or two building up supplies, step out once or twice for new supplies...get your holdout surrounded, run around for another day or two, then die. I still don't see the save options even though I read them in the patch notes. Maybe I wasn't looking hard enough.
There's always been a ton to like about the game, but I dunno. It still feels like there's some vital component of fun missing from it. I think it's because it's very hard to actually survive in the face of the horde, because you are always boxed in by things like fences, you can't jump out windows....So you're repeatedly doing the same thing, over and over and over again.
I got in way early so I own it regardless but....for me the game has not risen past its initial level of entertainment since it came out, despite allll the things they've done to it. The experience remains essentially the same.
