Yeah, I can't say I ever feel guilty when I've been railroaded into an outcome. It would be like me feeling guilty over something that happened in a film. It's not like I had any real agency in the matter. If anything it can sometimes frustrate me.

The Companion Cube example is kind of interesting though because you have to do it. I didn't feel guilty disposing of it, not because I was forced into it, but because I didn't really have any sort of attachment to the thing. Perhaps people who get attached to Companion Cubes also get attached to chirping nobodies in Journey? lolwut! Still, I loved that whole section because Valve expertly anticipated players' guilt and ribbed them with GLaDOS' amusing teasing and taunting. That's the mark of a fine developer when they can read the minds of their players like that. See The Stanley Parable for more of this.

So, guilty moments for me. They come in different forms.

First up: failing to hit the on-screen prompts in time and getting Norman Jayden killed (horribly) in the crusher on Heavy Rain. I could have redone the chapter but Hailey and I had vowed to take everything on the chin and keep moving. That element alone made the whole game way more intense. Everything was permanent, including death. Guilty as a result of poor reflexes.

Second: attacking (and later killing) Patches on Demon's Souls because the asshole had fooled me and because my brother and friends egged me on to kill him. There was no going back after attacking him and I was too deep into the game to even consider starting again. Patches was the only merchant in the game to sell heavy arrows too. This cost me a lot of time grinding a dragon's health down later in the game with standard arrows. Guilty as a result of poor judgement and listening to friends who have no care for the repercussions of my actions!

Third: sending Lady Boyle down the river (quite literally) with some guy I'd only just met (who's made out to be a lover or admirer of hers) to eliminate her non-lethally. As he's paddling away with her in the back of his boat, he says "You'll never know how happy you've made me. Someday she'll learn to appreciate me. After all, she'll have her whole life." FUCK. Oh Jesus. Joel and I both did this and both had the same reaction. Guilty as a result of poor judgement and trusting a complete stranger. (This is my most guilty moment I think)

Fourth: 2v2 co-op with Luke on Rocket League and jumping to knock the ball away from the goal (when it might not have gone in), knocking it into the goal with three seconds left on the clock taking us into overtime. Shortly after we conceded a goal and lost the game. Three seconds left. Three! Guilty as a result of poor judgement and a terrible 'save'.

Fifth: talking to a Dustman in Planescape: Torment who was terrified of death and thinking it was okay to tell her that I was immortal. It wasn't okay. The conversation had been going really well, so much so I thought I could let that 'interesting' fact slip but she just got upset, clammed up and told me to sod off. She never spoke to me again. I know this because I kept going back to her over the course of the game. Guilty as a result of poor judgement.

Sixth: this win on Frozen Cortex (I'm green): Guilty for giving no quarter and narrowly getting that last tackle. I think it was my opponent's first game too.

That's all I can think of for the time being.
