What I am about to show you might not even be considered a game by some of you, and I'm not so sure myself, but I've been seeing it so often that I've reached the "Why not" threshold, and now YOU get to "benefit" from it. You know whats tasty, and great in moderation? Cookies. You know what you're good at, what you've been doing this entire time without even really thinking about it? Clicking on stuff. What if you could combine those? (and throw moderation out the window because you'll wont be needing it where YOU'RE going) You'd get Cookie Clicker, and that's the...thing for today.
The cause of it all
The point of Cookie Clicker is to make cookies. You open it up in your browser and you make cookies by clicking on the giant cookie, but you can sell those cookies to buy things that give you more cookies over time, basically spending money to get money, if money were delicious and had no real dietary value (These aren't your fancy "nutri-cookies", its old fashioned chocolate chip, get ready to get pretend not real virtual fat).
"Why can't I stop?"
At first that's all there was to the game, but now there's achievements, upgrades, better art, cookie per second tracking, and game saves so you can stop to treat your crippling carpal tunnel before going back in to click the giant cookie some more to feed the endless cycle, eventually leaving you a hollow shell of who you used to be.
"Why couldn't I stop?"
FAIR WARNING: To some this game is pretty addicting, so I just want to tell you to not play this at your job or whatever if you work with computers, this is both the kind of thing you could have going in a browser in the background and the kind of thing some bosses would fire people for, and I don't want to be thought of as the guy who helped get people fired, I'm not gonna be a part of that, so this is me telling you not to do that.
Whoever thought up cookies and milk was a mad genius
