To anyone answering your post, yes it is. Mainly because if you look at us, we all have enough posts to tell you we have stuck around for a while, and are fans of the game.
Ultimately it depends in what you're looking for. I say its well worth the $10 to the point where I bought some friends the game, as well as myself.
If you haven't played since before scripts, I would say to start easy with it, and not overload yourself, or you will leave and never look back, because it changed so much.
If you are looking for a game that makes it very easy to mod in your own items, textures, and NPCs, then YES. this is a great deal. It's easily worth $20-30, but the $10 price tag makes it that much more affordable, and better of a deal.
Give it a try, and if its not for you, its only $10.
