Yet, most people that I know that play FPS games are casual gamers... You know, those people who buy whatever shit is popular and only play those games when people visit their houses. Funny thing is that they're all those grown men who likes violence and stuff not that girl/kid stereotype people have from casual gamers. Many people prefer some casual local multiplayer fun than an immersive single player game or an every day online competition to try to be the best at the game and I particularly think that an easy to play FPS is just perfect for casual gamers
