I do not like such "rankings". I mostly write Addons for my own usage because i'am tired to use this terrible gamepad interface in a pc-game. Two of them are now public and i try to keep the quality up. Sometimes a ingame donation comes via mail and i'am happy - thats really nice, because if i'am "playing" i mostly coding instead of making gold pledges or level up to V16.
One thing would be really nice - a triple enlightment for confirmed (and well used) addon-authors to compensate the "lost" playtime.
P.S. A npc with my real name i already found ... in a cave ... and i was quite surprised
