How big is the world and can you enter those houses and just kill everyone if you want? and still complete the game.

16 square miles and yes, you can kill anyone except a very small number that are integral to the main plot

you can go in any building

to join the dark brotherhood, I had to murder someone

Go outside

Ahhhhh. no wai

I started playing Morrowind again 2 nights ago...I''m so hooked. I really want to get Oblivion, but it's $80.00CAD

Morrowind is a classic. I see my self getting back into it years from now
Noumenal, are you still playing this game?
I picked it up again today. Got myself a new palace. It rules

heeeee heeeee heeeee heeeeeeeee heeeeee heeeeeee :D

Ya know, you're laughing. But, look at my house



While you're knee deep in snow, I'll laugh at you while Im on the top floor tending to my indoor garen:

heee heee heee

(you know it would have been better without the pictures-- funnier)

ace. repped (for the humor, of course, not the "house"). :D

Yeah, you're probably right. I posted the pics anyway just so everyone could see how awesome it is!
And thanks for the rep

Wow, how embarassing for me in retrospect. Well, I don't regret being excited about that game - it kicks ass. I don't play it right now. I "beat" it and quit a good while ago. I'll probably pick it back up again after I ugrade my PC and can crank up the graphics.

So, can you, like, own your property in Oblivion and shit?

Because this was not possible in Morrowind, i guess

Oh, but what a game it was. An absolute classic in RPG genre (well, maybe besides Gothic II. and Albion)

Yep, you can own houses. But, there's only a small number of houses you can buy in the game (around 10 maybe?)
It wasn't possible to own land in Morrowind, but you could just go in someones house, kill them, then call the house yours. This won't work in Oblivion because gaurds will come in the house and either make you pay gold or arrest you
