Diablo is one of the best games. Sure, it's violent but it's fun. Though sometimes the gore can get out of hand, such as when you encounter a monster that is 'fire enchanted' killing them causes them to explode in a gorey mess. Some skills such as the necromancers corpse explosion has the same effect. So gore is a pretty big issue here. Language,drugs,alcohol, they are not in the game, besides a bar in the second act. The game can and will make your hand go numb if you play it to long however, since it involves lots of clicking both mouse buttons. The game is pretty long and will take time. There are very minor maybe you can call them sexual issues, as in the first and rarely in other acts you encounter female undead warriors who are scantily clad, if you even look that close. And your first AI partner you can recruit is a bit the same. The first act boss however is another story, as she is immensely tall and show her chest completely. However, chances are you won't notice as you should be to busy trying to survive her attacks to pay attention. There are some nightmarish things, such as giant bugs,the act 2 boss is a key one here, large mosquitoes,swamp monsters,big foot like beasts etc..though admittedly, the boss in the 3rd act is nightmarish crazily. The cut scenes are also that you would see straight from a horror sci fi movie so beware there. It's a game that is incredibly fun,which is doubled with a online friend, and one you should try before you buy.
