I have played Morrowind, Oblivion, and Skyrim and I am looking to play Arena and Daggerfall but I am a little wary because I have heard they are very difficult. I did not have very many problems with Morrowind once I read a few build guides, and I have played Fallout 1 & 2 and not had too many problems.

I am just not sure I want to try playing them if they are too difficult for me to enjoy them.
