8 is Dues Ex?
Deus Ex: Human Revolution?
As The_Liquid_Laser guessed my game #8 is Deus Ex: Human Revolution.
Transhumanism is a topic covered sparsely in entertainment. This happened mostly in books, especially following Neuromancer from William Gibson. That also led to Shadowrun. But I don't see much recent novels covering this. In movies some old movies like Robocop had this topic. Nowadays only some Anime (like Blame!) dive into that. And that although human enhancements through technology are actually very possible these days and this might change our societies in the next decades.
In gaming as far as I know only the Deus Ex series has Transhumanism as a theme. It also follows other ideas of Gibsons novels, so we have a dark future controlled by international corporations that form the world for their profits.
But that alone wouldn't make a good game, Human Revolution is not only a good game because it makes a pretty good plot out of the basic Gibson-like thematics. It is because the game gives you a lot of freedom to decide. Every problem can be solved in multiple ways. You stand before a closed door? Hack it. Or find a ventilation shaft to crawl through. Or talk the guard into it to let you in. There are always multiple solutions. And that freedom feels just great as a player. I as a player form the adventure, not the game-creator.
I played the Directors Cut at the WiiU and I cannot say if that was the case at original release, but the game had a high level of polish too. I encountered practically no glitches. For a complex game like that I can appreciate it.
