If you are looking for a rich engrossing RPG romp through the sword and sorcery heavy world of D&D, Neverwinter Nights is something you should get. And for the price of free why not?

Nope. Just free for the next 19 hours!
Grabbing it! I've never played it. Is it Free-to-Play? Is it a MMORPG or single player?
Oh. :( Anyway, I deleted my comment that you replied to, because I added a second question to it, which is why you see your reply then my comment.
Why are you frowning at that Greg? It's free! Snag it in the next 19 hours and it's free.
Oh I think I see-- free-to-play is a kind of game model. Free and free-to-play are not the same thing.
You may have thought based on Jon's reply that you can only play it for the next 19 hours. But that's not the case. It's FREE for the next 19 hours. So grab it now and you can play it forever.
But that doesn't make it free-to-play. If that makes sense.
Oh but also, it's the next 41 hours. It's a two day freebie.
Huh, thanks for letting me know. Updated the post. It said 19 when I was there earlier.
I guess they either put it in wrong (that's what she said) or changed their minds.
