I’d say it was more subtle about it. Or maybe it’s an expectation point - if I know I’m playing a game in a brutal post-apocalyptic setting, expectation adjusts.
For all that F3 is an irradiated hell - F4 even more so - I don’t recall either game burning someone alive in a long cutscene. Granted, I did that many times with a Heavy Incinerator but as they were all Talos or Enclave, it don’t count. Similarly, you can’t go a hundred yards in W3 without finding corpses hung from a tree - it just felt nastier, but maybe that’s just me.
