This game is awesome. The detail that has gone into making it is really amazing. Unlike some games, when you make modifications to your motorcycle, they show up in the cut scenes and even the loading the screen.
The detail to the environment, even zooming in on telephone poles and trees, you can see the wood grain and detail.
Like all games there are some glitchy issues. On occasion when searching an area you have to back out and start again for the item to be identified. Sometimes when you rescue someone they stand there and stare at you and you have to restart the game and replay the rescue to get it to cut to the dialogue.
One of the biggest issues I find is that sometimes while being chased by a horde, trying to select a gun instead of the melee weapon doesn't work, and it will revert to the melee weapon causing you to get overrun.
Otherwise, the detail, mechanics, storyline and all around construction is amazing.
