Thief Gold

[Bridge]

I figured 'screw this stealth business, I'm gonna run around like an idiot' because it worked.

What difficulty do you play on?

Constantine's mansion indeed doesn't make any sense. However the reason why will become apparent later in the game.

The levels in gold didn't seem to fit together well at all, like the textures were just random and the rooms didn't seem real.

It seems that way cause it's an old game and the textures are of low quality.

I tried playing on expert, and it was impossible because whenever I walked behind a guard as quietly as possible he just turned around and killed me. So I think I was playing on normal or hard.

And I know that's the reason for the crappy textures, but it really ruined some of the immersion for me because the levels just seemed slapped together with little attention to detail.

Perhaps you're experiencing a bug. The textures are not great but they have a lot of aesthetic appeal. Also, the level design in all three Thief games is superb and very meticulous in my opinion, with some exceptions.

About Dishonored, I think it looks rather good too but someone said it looks like Thief with cheats and I am inclined to agree based on what we've seen. Still, it seems like a lot of work has been put into it and I am probably going to buy it when the price goes down. A no powers/no kills run like I'm going for will probably be a fair challenge.
