Is it worth getting the boxed Daggerfall on Amazon for ￡175? I know it's free online, but I like having a collection. I want to ask here because I know you guys will understand that it is a hard choice. Is it worth it to spend that much just for the sake of having a collection?

I think only you can answer whether or not it's worth it to you. Personally, I would have a hard time justifying that price. However, if I was building a collection then the price might be no issue (as people spend much more than that to obtain items for their collections).
