Don't lie to yourself. We've all been there.
Games are far more complicated than what they used to be. They've become something more than what we just do for entertainment. We're watching stories, interactive stories unfold with ourselves being the main character more often than not.
So, it's not that uncommon that we just might become a bit more attached than normal with some of the badass, attractive characters we interact with in-game.
Right, now that my excuses are established and out the way, let's get on with it!
There will be (very) minor spoilers regarding certain characters. I'll try to gloss over most, but you have been warned!
