Here is a list of the pro's and con's of gun
1. You can explore the land in search of side missions and gold to mine
2. There are lots of side missions that are fun
3. There is a wide variety of weapons
4. Lots of cool shoot-em up parts of the game
5. Throwing dynamite near somebody's feet and watching all of their limbs fly up in the air is quite amusing
con's
1. The blood in gun looks really outdated and weird
2. You don't get to keep one horse with you through the whole game because sometimes after missions they dissapear so its basically grab whichever horse is closest to you
3. There isin't very much land to explore
4. You can increase your stats but it barley makes any difference
5. When you have men with you to help you fight they hardly ever get kills and usually die right away.
conclusion: Gun will offer you some great thrills the first few times you play it but after that it gets boring, so if you want to play it I would recommend renting it.
