Yes, one Escapist poll showed it as the best game of all time and another (is bound to show it) as game of the year.
But then, I don't like Fallout, I have never played the Witcher and I love Oblivion.
But despite that, it is a great game in its own right and worth the money.
Get it on PC though, the mods are already good. Unless you want to join the crowd of sooks who bought it on PS3 just to complain. Seriously, why would you buy a TES game on a console? You deserve lag and glitches just for making that decision.
