The game so excellent that it got a fucking Oscar nomination for one of its songs. To me, this is the pinnacle of Rockstar — brilliant gameplay mechanics, a world that while not the biggest, still feels full, and the ability to play poker, cheat, and shoot the other guy when you get caught.
Even the silly DLC — Undead Nightmare — was brilliant and a lot of fun, unlike the millions upon millions of inferior zombie games made throughout history.
The story was haunting, and the setting — the Old West — is still shockingly underexploited for video games. A brilliant game from a brilliant studio, and one I recommend to everyone.
Even if some of the horses are suicidal.
