Fallout 3 is a masterpiece considering its time period, and most if not all bugs are product of newer and newer hardware and lack of updates. If you insult fallout 3 for lack of updates, you may need to be reminded of the game these forums are based around. The fact the game is moddable enough to receive a complete patch via its own mod system is incredible.
do you want a masterpiece within the time period, with a game that is actually fun, fixes a lot of bullstuff issues with fallout 3, has an actually engaging story, fun map, and actual freedom?
play fallout new vegas
this video demonstrates every single issue with fallout 3, if you think the "epic gorey" vats system is cool, then good for you, but the story? its absolutely terrible, game progression is ass, theres no real difficulty or challenges and the only good parts, are the little side stories that you must find yourself in the huge map
the literal only reason this game is decent is because of the hard work of modders who put the time to fix the stuffty issues within the game, i dont need bethesda to fix and update the old stuffty game but you can clearly see the repeated mistakes from fallout 3 in fallout 4 and fallout 76.
i dont think i have to even elaborate on the bugs, anyone who plays a bethesda title expects bugs now, fallout 4 on launch was very buggy, and dont get me started on fallout 76
