What Degony doesn't like in most rpg/mmorpg is the lack of realism:
All my respect goes to D&D and all the pen&paper games. They started these games, but because everything had to be calculated on a piece of paper and throw some dices, there were some limitations. It's too sad, that the gaming industry is only improving the visual aspect of the game, but the fighting system, leveling, item drops, etc hasn't yet suffered any major changes. Yes, it's true, most games have their own system, but it's not that different from D&D. Adding minor changes and modifying some naming conventions only for the sake of being a bit different, doesn't help that much.
Degony will try to be as realistic as possible. There won't be any hunger, fatigue, sleeping, taxes and other things that aren't fun at all in real life. So the idea is to make the game realistic and fun at the same time, even if that means dropping some realistic facts. Besides the fun element, there's also the need for preventing players to exploit different aspects of the game, for instance equipping yourself with the best gear in the game when you are only level 1 and you just started the game.
