Pretty much since the video games kept score, it's been the obsession of a lot of people to get as many points as possible to show that they were the best player. And an arcade game called 'Giga Wing' takes that to its crazy extreme.
In Giga Wing, you have the ability to reflect enemy shots back at them, which allows you to collect these shield emblems, emblems that when collected increase your score multiplier, and your score multiplier increases the number of points you get every time you shoot down and enemy ship. And very quickly in this game there are lots of shots and lots of enemies that explode into a shower of pickups when hit
Seriously, it's enough anyone to get a score in the hundreds of millions.
But that's nothing compared to people who are actually good at the thing. Heck, you have to go through the whole game on one credit to see the 'real ending', and if you manage to do that, your score rockets up to the crazy-high territory: the Trillions.
Needless to say that I'm probably not going to achieve that any time soon. But maybe you can, if you can find a Giga Wing arcade machine (or a copy of the Dreamcast port).
