I have to say I also enjoy this game without the gore. IMHO its completely unnecessary. The game focuses on immersive player to computer interaction and story. In fact, the expansion has so little fighting that you'd be bored to death if all you were looking for is blood and gore. This game isn't a FPS mixed with a RPG. There's plenty of those and they offer far more gore because fighting is an integral part of the gameplay. To me that makes this game more casual and it allows you to focus on problem (puzzle) solving and story.
In fact the most successful MMORPG has no gore and that's where a complain should really be levied. After all you're either chatting with other players or fighting (grinding) 95% of the time. That's a case where you need some additional oomph to liven it up.
As for the option to put in gore. What would you rather have developers spend time doing: put in a gore option or additional content? You can't have both. Its not like they're bored sitting around looking for something to do.
exactly. To me, too much blood and core take away from an otherwise great game. Take God of War for example, I love games about mythology, but God of War has so much blood and gore that the game is not enjoyable for me. Games don't need to be gruesome to be good.
