A long time ago I made a bit of a rant about player choices in games. It actually wasn't such a very well thought out one and I failed to make any good point about it. I tried to think how to develop those thoughts better since then but I never quite got it right. Fortunately, someone else did! His name (at least in the interwebs) is MrBtongue and he made it into in a YouTube video which you can see below. Just a warning though it does have some spoilers about Fallout 1 and Mass Effect 2.
If you like this one, I highly recommed to check the rest of his channel. There are some good stuff there. 🙂
