Well, if you haven't seen me around the gaming forums I'm known as a MMORPG freak. I can give a list (and did in the xfire forum) of all the free MMORPGs out there. I can even give a summary of the history of MMORPGs (i partially wrote the article in wikipedia)
I've also played many P2P MMORPG such as WoW, Everquest, EVE, DarkSpace, etc.
One look at the Sins Lore and it's obvious that this game can become a MMORPG, but not just any mediocre MMORPG, a GREAT MMORPG. One that might rival the giant EVE Online. Currently the history I've seen are substantial enough for a good background to a MMORPG, and the large amount of ships/stations/platforms also contributes to the potential. There are many worlds that a player can explore.
All someone needs to do is improve the textures to EVE caliber (if not already), implement the MMORPG standard interface and gameplay (almost all MMORPG work in a similar way). Add servers that hold over 500 people (preferably 1,000). Implement NPCs/missions, a universal war (already in game), a good MMORPG engine and finally a extensive universe to explore.
At this new age of MMORPG, there are WAY too many fantasy MMORPGs. What we need is more science fiction MMORPGs.
Just thinking out loud here
