Due to the fact that It's designed on an older game engine that is extremely limited on detail level lol that doesn't even use normal maps
Normal mapping - Wikipedia, the free encyclopedia, uses a simple point/click key control interface that makes it easy to hack using a packet editor (not that I've done that before

) and the fact that they already made over 20 times what they spent to create the game I feel that they shouldn't charge a monthly.
If they got rid of the monthy fees I probably would consider trying a game that basic.
