Third point which most MMOs DO have. A well balanced economics system. With NPCs to interact with like bakers, black smiths, and all the likes. This is what makes the world feel alive enough to actually have a character (twelve sky2 Gold) in there that you can casually RP with as a civilian. And
There is of course a Sixth point in Twelvesky2. And many more. Like. Casual looking gear. Unique appearances (Good Character Creation). Plenty of Animations. Open Game, not the usual Good/Bad. Most MMOs go for. Allowing a higher freedom to what your character (12sky2 Gold) may actually be without Pre-Judged. There where 3 factions, but the lore was so tight on all three, that if you wanted to RP as one.
