Decent game, somewhat short
Gun was a decent game but it was somewhat short. I completed the entire game in just 1 session of about 6-7 hours. That said, there was a fairly broad range of environments and missions, though the story was linear. The quests were varied and generally fun, but a few required several retries due to difficulty or poor control. The story was one of the weaker aspects of the game, but it did a good job immersing the player in the look and feel of the wild west. Replay value was almost nil and I wouldn't want to replay it on the 360 for the achievements either. The graphics and sound were average to good for the PS2.
