Simply, there is no way without mods.

No Morrowind is a one player game, but I've heard of a failed beta of an online Morrowind for the PC.
The Lord's Mail is not in Oblivion. In Morrowind there is a book that describes many of the artifacts you can get in the game. Bethesda put this book in Oblivion too, though many of the items do not appear in it. So you could only ever get the Lord's Mail in Morrowind (and Arena + Daggerfall).
All of "arena" is not as graphic as morrowind by quite alot. So everywhere you look morrowind is going to look better, but they are both fun.
Get action replay.
You cannot become a Frost Atronack on Morrowind, the best you can do is summon one.
No.
Yes, you can become a werewolf in "Morrowind: game of the year edition", as it comes with the "Bloodmoon" expansion.
You cannot play morrowind online, even with a mod.

There's no way to multiply items, blocks, or anything in Minecraft P.E.
You can't, you can get more items in the presents on the streets while you're walking your dog.
