For me, it depends on the developer's reputation. If I know the developer tends to release buggy games at release (Ubisoft, Bethesda), then I'd wait weeks, months or maybe years after release to get it. If the developer has a relatively good track record on fixing games (Rockstar, Rocksteady) or with rare bug instances (Insomniac, Naughty Dog) then I buy it Day 1.
