can never go wrong with violence

Heresy, even though that level was basically a puzzle it freaked me out the most. The screams from the human wall were insane i was disturbed while playing that circle.

I can tell you Anger is my least favorite level, and the only puzzle (the one with the gears and the platform with the fire blazier coming up as you move it) that pissed me off.

If I had to go with the most interesting, it would definitely be Gluttony...but this is my favorite one...and that is Violence.  The three separate rings were very differentiated, and the Woods of the Suicides was genuinely creepy for me.

I would say Lust. The giant penis spire rising out of the void solidified it as my favorite.

Man, this is just wrong.

Lust with its awesome penis tower, tho Woods of Suicide was pretty creepy in Violence

Penis. 
 
Tower.

Anger was my favourite. I love the music that starts up just before you cross the River Styx. 
 

Lust...almost turned me on.

"Lust...almost turned me on. "

Definitely Heresy. The statue of Epicurus was awesome. Also, loved when the camera panned out as you began to enter Dis.

I liked Violence and how they split the circle into three sections. Anyways, has anyone looked up Dante's Purgatory and Dante's Paradise? Apparently those are split off into multiple tiers as well, each area themed after flaws for purgatory, and virtues for paradise (sins for inferno). I can see why the sequels are certainly possible, but from reading about them, I don't see how the gameplay would translate to less violent parts of the three 'kingdoms.' Let's say Lucifer does take over the kingdoms, then wouldn't it just be Inferno all over again?

Lust, baby. S'where I live every day.

I really liked Violence.  Not only did I think it had one of the more profound reveals of the game, but it was a solid level that contained a lot of really good combat setpieces. 
One thing I hated was having to push that platform up the hill whilst never-ending enemies spawned.

Limbo was kinda awesome due to the introduction of the whole concept.

"Thinking back, I liked Greed as well. But really, Fraud and Treachery kind of get weak. I liked how Treachery was frozen, but they don't utilize it and Fraud,  the developers just ran out of steam. "
