The Elder Scrolls V: Skyrim

Skyrim is the game that turned 'open world RPG' into a mainstream genre. Bethesda built a Nordic fantasy world so compelling that players have been modding, replaying, and re-buying it for over a decade. The freedom to be anyone — a mage, an assassin, a werewolf, a homeowner — is intoxicating. Yes, the combat is clunky and the bugs are legendary, but no game has ever matched the feeling of cresting a mountain at sunset with your own custom character and just existing in a world that feels lived-in.
