Being concerned about morality in videogames like this seems kinda silly to me anyway. There are tons of games where you murder people constantly and no one is like "oh but that's awful cause that's not legal irl" :P
That's why in Germany you kill robots. Robots have no rights (yet) Same for zombies... and weirdly Nazis.
While Bethesta games aren't that stable out of the best, I think most people give them leeway as the scope of their games are by far the most ambitious. Given enough time and millions of users reporting the bugs, they are usually become rock solid.
That said, other than some funny and weird shit happening, my first Skyrim game didn't encounter anything that broke it. The worst that happened to me was a bugged quest that didn't remove itself from my quest log even after finishing it. Also, backward flying dragons and mammoths raining from the sky aren't bugs to me, they're hilarious features =P
I don't know. I can see a purpose in Animal Crossing that you can get enjoyment from improving your situation. But yeah, from what I read of TL, it's more akin to keeping ants and just looking at them.
EDIT: Saying that made me remember how 4 highest-level AI battle royal in Bomberman 64 was a blast to watch.
I understand the feeling Mesh. The missions in GTA IV were the main reasons I dropped the game. They never felt fun and I often failed them due to the most banal reasons. It felt even worst since I had freshly finished SR3 whose mission I feel were much better designed and overall fun.
