The game is good but difficult as you can't save on any of the games. In the first game Mad Dog McCree you are going round the town to try and find Mad Dog but you have to do things like find maps and help the sheriff get out of jail.
The next game Mad Dog McCree II: The Lost Gold allows you to pick one of three people to help you get to Mad Dog and the lost gold but they all have diffrent ways to get there.
An finally The Last Bounty Hunter. This one is easily the best as all you have to do is bring in crooks dead or alive (You can choose). I did notice some blood in this one. If you don't shoot any innocent people you want see though.
The games are very good as they are nothing too violent for seven year olds.
