Probably one of the most "basic gamer ass" questions I could ever ask, but felt like it anyway since hell it happened to me recently so I figured I'd make a thread.
I was on the final boss fight of Doom Eternal's "The Ancient Gods – Part 2" expansion, got the boss down to his last health bar, and bam the game suddenly crashed out of nowhere. Now thankfully the devs were courteous enough to put in checkpoints at the different phases of the fight so I only had to start over from the beginning of the phase I was on, but man was that still one of the worst spots for the game to suddenly crash at.
Now going back in time for the next related story, back in 2008 when I got my Xbox 360 and a copy of The Orange Box I kept experiencing freezes in the same spot during the Half-Life 2's final level (if you've played HL2, it's the spot where you have to take out a strider at the end of a giant hallway area). Apparently this was an issue Valve did patch, but the problem is when I first got my 360 I didn't have it hooked online yet since I didn't have a spare ethernet cable until a bit later. I was pretty annoyed that this kept happening but I still wanted to see the end of the game so I could play HL2: Episode 1 the following morning so I just looked up the rest of the game online. I did get that ethernet cable a little while later and finally went back and finished HL2 proper, but on that specific weekend I just wanted to keep playing without running out to the store (related: I eventually sold my copy of The Orange Box when I later bought all the games that were on it on PC, though part of me wishes I kept it just because I'm kinda curious how these games look when played on an Xbox One or Series X, and because the 360 version of TF2 is the only way to experience a very vanilla version of TF2 nowadays and I'm curious to see how TF2 would have held up had it never gotten all the updates it got on PC).
