Neverwinter Nighters anyone?

Gaming tonight? If I can it will be late.

Is this the same game that's on Steam?

You're probably thinking of Neverwinter, the MMORPG that's relatively new. We're talking about Neverwinter Nights, and old RPG from way back in 2002.

Neverwinter of course would serve the same function. A GM can create his own scenarios and any GPers could join up and run through a scenario together (as well as thousands of other player generated stuff) and it's Free to Play

I would say it is beyond free to play, it is perhaps the most immersive tabletop experience I have ever had on a computer.
