It hurts a lot to loose character you played for 2 months, or for example 50 hours. Sometimes i could not handle butthurt and savescummed after some stupid and unnecessary death, but allways i just could not take any fun from that character anymore. You did it once, you will do it again. There is no danger. Everything can be solved without effort if you can try infinite times.
Thats harsh part of non-savescumming mentality, but there is also a bright one. If you sudenly meet some unexpected danger: mininuke grenadier in bad place, horde of shocker brutes and hulks behind a corner when youre low on stamina, painfull burst of 5.56mm from mil turett or chicken you barerly survived. If you meet these things with your beloved hero, and somehow survive, escape, or destroy danger, you will feel emotions like not many other games can provide. Its a turn based game, and if it wasn’t, i think my heart would burst a few times when i was endangered, knowing there will be no restart, no another try. It just makes you really care about otherwise “just another stupid game, thats not real”
For me, most of my characters deaths were lab turrets, most of them due to pressing too many buttons too fast or forgetting that i left some of them untouched. Since some time, i allways explore labs with heavy survivor suit AND plate curiass over torso, together with heavy survivor helmet padded with everything. It saved me dozens times. For city exploring, usually going with just light survivor gear is more prefferable.
