See I guess that is how I am different. I have three favorite TV shows, Scrubs, House, Burn Notice. I don't even have a antenna in my house so I just watch TV on Hulu. So what I tend to do is go to wikipedia and read what happened on the most recent episodes there, but it never makes me not want to watch an episode.
That's how I take all these spoilers, yeah they reveal a lot but I can still enjoy it. Even more so because it's an interactive experience where I won't actually do the same things as various spoiler videos do.
I played through Mass Effect 1 almost (on my last playthrough now) 4 different times, and not once did I feel I was being robbed of any sort of experience, even during my NG+ run. Admittedly I did skip through a few conversations, but even then I never felt less entertained.
I can always extract logic and memory from my immediate encounter. It's a skill, I admit, But I found it has always served me well to be able to just shut it all down and enjoy something for what it is at the time, rather than focus on what I may already know.
