For instance, compare and contrast FO3 and Alpha Protocol. Alpha Protocol was purportedly pretty buggy on release, but now it's been patched and most of the bugs are squashed. FO3's 1.1 patch introduced a bug that prevented the game from using more than two CPU cores without crashing. It also made it so you couldn't target grenades or rockets in VATS any more. Neither of these bugs have been fixed as of the 1.7 final patch.
