While we at Co-Optimus do not generally condone the act of competitive gaming, which, by definition allows you to dominate another player; there is a kind of co-op that does include domination, one we would like to paste a label on. This type of co-op can, if used correctly, be used against that game-hog sibling, spouse or significant other. Co-optimus would like to proudly introduce: B.Y.O.B. (Bring Your Own Bitch) co-op gaming. We've looked at a few examples of games that created the B.Y.O.B. co-op genre, all the way back to the days of the Sega Genesis, and culminate the list with recent entries on systems like the Xbox 360 and Wii.
This is the official Co-optimus.com list of B.Y.O.B. co-op titles. (This editorial is rated P for Profanity.)
