I’m currently enjoying Day R, which is a hard-core post-nuclear survival game set in Russia. (And originally in Russian - even the help files use Russian-language screenshots and many of the translation are… let’s just call them less than fluent.)
I say hard core because even on the easiest setting, I’m having trouble just getting around without dying. It’s becoming clear to me that achieving game quests has to take a serious backseat to finding water and building fires. Head to the next town only after you’re discarding food and water because you can’t carry it all.
