Favourite game to be EVIL in when you had the choice?

I'm playing through inFAMOUS right now and loving it.  As usual I'm starting out playing it good, and on my second playthrough I'll dally with badness.

But it struck me what was the best game to play bad in when you had the moral choice options? So GTA would not apply here.

For me, it was the original Fable on my PC.  Damn I loved it as my character's horns gradually grew out of his head.

I probably have to say Fable 2. It was cool how your character changed (i.e. the horns, their skin turning gray and gross) and it was actually fun being evil in that game because of the things (like quests) corresponding to evilness in that game.

I enjoyed going along the renegade path in Mass Effect.

fable 2, fun to see bad things happen to the villagers then have them say "OH I LOVE YOU!!" cause of my awesomeness.

I don't really enjoy playing as evil in any game, but I didn't mind playing as evil in Fable 2. Though I have to say that a game like Bioshock was impossible to play as evil for me...I don't know why, but I just couldn't bring myself to harvest the little sisters, even after numerous "good" playthroughs.

Animal crossing.......beat tom nook with a shovel......i am playing that for the rong reasons. to be honist ive never played evil its not in my nature im too much of a goody 2 shoes

Like alot of other people I dont usually play as evil but i must say watching the people of megaton meet their doom was totally awesome.

Baldurs Gate I reckon.

Black and White: There was no greater feeling of being evil than to sacrifice people to give you greater power.

probaly the orgial fabl devil horns that were awsome although being evil in infamous looks like fun and that i am pickig up this week

I don't think that there has ever been a game that I wasn't enjoying myself more playing as a good character. I will always take the evil path afterwards, but being good feels much more rewarding to me.

I'm a very evil person in every game I play.

On the Tattered Spire quest in Fable 2, when it's all like "Feed the prisoners, or let them starve." I just flipped them off and "Vulgar thrust"ed until they died.  Yeah.

I almost always play evil first, guess I like variety when I can get it, as most games force you to play as good.

I always loved playing evil in the KotOR games, forcing Zaalbar kill Mission was just.... evil.

I never find myself playing evil very much in any game with a morality base. I toyed with it a bit in Fable 2 and Black & White a little. KotOR was another one. 

Civilization, doy. Nothing like plunging the world into nuclear Armageddon.

Bonus points if Gandhi's your leader.

Dungeon Keeper

Also, the best game ever created that nobody played.

I don't usually be evil but like Kush said, after a little while I started to despise my Fallout 3 character so then I created a new good character.

Wow, I do pretty much the same as everyone else.  It's pretty surprising, I'd (for some reason) expect it to be the other way.  Damn "gamer" stereotypes...

Yap. There was only a game where i loved to be the bad guy.

The Knights of the Old Republic... The bad ending was so egotistical that i couldn't pass out.

Huge spoiler for Kotor ahead *************************************************************************************************

Bastilla says something like this, near the end...

- Come to the dark side, and we'll rule the galaxy. 

You say:

- How do i know you won't betray me?

And she goes:

- I need not deny my passions anymore. i love you. Malak is weak... Together we can rule the galaxy, as master and pupil.

And in the end...

- The republic is finished... On the run... bla bla bla

(...)

"All hail Lord Revan!!! All hail Lord Revan!!!"

(...)

And an awesome clip of a sith massive fleet gliding to battle...

:')

It paid off to be the bad guy...

In the rest of the games, i generally act as i am. A goody two shoes. Can't help it...

Most games don't actually portray "evil" as much as they give the player the option of being a selfish dickwad and calling it evil.  Most of the time the choices are help or not help, steal or not steal, etc...which aren't really what I'd classify as evil.  There is one situation however which made me feel scummy for an hour after I played through the scene, though.  In KOTOR...
well, there are spoilers galore ahead, so I'll just link this video I found on YouTube.  The original poster of the video agrees with me.  "That's just so gloriously messed up"

What about overlord? It was quite entertaining being evil in that game, but there again it was really a choice between the degree of evil you wanted to be, rather than good verses evil. I am going to have to say Knights of the Old republic for choices.
