This is a list of things NOT to do while playing Morrowind (or at least until you've beaten the game.)

1. Don't try to attack the census, unless you plan for this to be a VERY short game.
2. Do try to answer questions to get your class. Create your own and select the stuff you want.
3. Don't attack Caius Cosades. Don't know the guy? He's the dude that the census tells ou to meet. He's one of the most important characters in the game.
4. Did you ever find a big door leading to a place called "Cavern of the Incarnate"? Don't go in... TRUST ME.
5. When in the cavern of incarnate, don't attack the spirits. Although many people don't realize it, GHOSTS CANNOT DIE.
6. Don't sell the item called "Package to Caius Cosades". I can't tell you how many people lose their games because they sold or lost it.
7. Don't steal the stuff that can be bought easily. Once you steal something, that object is permenantly marked. Not just that item. Every item of that kind. Steal a plate? EVERY plate is stolen!
8. Ever go to Vivec's High Fane and wonder what's behind that locked door? Keep wondering... For your own good!
9. Don't ever, EVER go into the Chamber of Heart of Akhulakhan unless you have distinct plans to complete the game then and there.
10. Don't try to fight Vivec the second you find him. People, he's a friggin god! And you wanna try to kill him with an ebony broadsword!?
11. if you get expelled from a guild, and welcomed back in, don't screw up... You only get one extra chance.
12. Despite the phrase "Size doesn't matter"... It does. When you see a large monster running at you... You should run the same way!
13. LAVA BAD... LAVA VERY BAD.
