If you wanna stick with IE, or can't switch, I'll warn you right now, while most of this site should work with IE, stuff might come up buggy, so you might not enjoy it as much...
Neverwinter Nighters anyone?
Gaming tonight? If I can it will be late.
Is this the same game that's on Steam?
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.
