One of the bigger and more professional games made with Torque3D. It is supposed to be an MMORPG sandbox game, but from what I know so far, it is more like regular multiplayer at the moment as they struggle to maintain lots of players in one game. I think the MMO game is still to come as their first game is called "Life is Feudal: Your Own" and is supposed to be a small part of the final MMO game that is still to come.
Graphics look very nice even though it is mostly procedurally generated and not manually placed. Technically it also offers lots of possibilities like terraforming, crafting, base building etc. Probably one of the best games made with Torque3D, but beware it is not for casuals as it is supposed to be realistic, so building and leveling up can take very long from what I have seen.
Update: There are multiple games with this name now:
The first game that was released, as a predecessor to the MMO that came later:
The MMO game:
Similar to the other games, but as a strategy game focusing on city building etc.
