I've always been a big fan of games. I invented games to play on the schoolyard with my classmates in first and second grade; I played Atari games and Nintendo games and games on the computer. Games are quite often a lot of fun.
And... they can also be really, really challenging.
I remember how there were a few games I'd play as a kid that went on for a really long time, and I'd always get killed before getting to the end. Ninja Crusaders on Nintendo was one... I only ever beat that game once, after playing it for what seemed like forever. I got pretty good at the first four levels or so, but once I got to level 5 my survival rate went way down... and reaching level 10, the last level, was an achievement in and of itself. That one win I finally got felt like I'd climbed a mountain.
Most games that were that hard I never even bothered trying to beat. You'd get good at the first few levels, then keep getting beat at the same spot, and much of the time you'd just give up and go do something easier.
The pick up game is just like this.
