More like it.
Based on what the game actually has to offer, having owned one, I see this price range to be more appropriate. It's not a bad game, but to say T3 is a ~4K+ game is a stretch to me. Play one, and you'll see that it just doesn't have the wow factor and loses steam quickly.
That said. I'd own one again, but sure as heck wouldn't overpay for one.
