Casual gaming last few years has earned this reputation of not real gamers or some 99 cent game on IOS. Or Wii Sports. While the "Hardcore" go play "real games". Been given this rep as it's killing the industry. No what hurts the industry is shovelware and AAA games that put more graphics than gameplay into it(Crysis 3)
Well I am going to list a few games that are casual. Call of Duty or any FPS multiplayer. Mario,Sonic,Sports games,Street Fighter many download games. Now before you freak out. Casual gaming is a game that you can pick up and just play have fun either by yourself or with friends. The gaming industry was founded on casual experiences. Pong,Pac-Man,Donkey Kong. Atari,NES. These systems many of the games were meant to be picked up and just have fun right away. You also had games like Ninja Gaiden,Mega Man,Final Fantasy that took more effort and time and skills.
I can invest hundreds of hours in a RPG but also turn around and pick up a Kart racing game or Pinball. Shovelware and Casual are not the same thing. Shoevelware can ever be a bigger budget series but released every year to milk every last drop. Still the same game for the most part and using a graphics engine it first used 7 years ago. Games like Wii fit are kind of a gray area to me. Fitness games been around since the 80's. I can see where it would fit in. I can also see where people lump it with Shovelware. Havest Moon is a 20 year old series and very casual while also investing time and effort into but a very relaxed and simplified type of game, Same as Animal crossing. Farmville is the shovelware for stealing a concept and making you pay real money and a bad clone to boot.
I don't really care for the labels gamers brand one another. Just that I feel casual gaming itself is fine and gaming was founded on having fun and the primary goal of most casual games is to relax and have fun.
