Why did you include PC??? We aren't talking about PC games, and plus PCs are an ever evolving platform unlike consoles. There are no generations as so many products are manufactured at the same time and overlap. With the 173 of only Cube, Xbox, and PS2 titles, even then it is questionable.

Shooting at creatures and seeing green goo doesn't count as blood in my book.

The game isn't even done yet, so the rating isn't official.
I'd wager you could split the list in about half by taking games like the thress above out of the list.
