A game? Well, the only real difference between this and the standard double-line-FLI is that the (double) lines are shifted to a position where the least color is lost. Ideally you'd want to color each pixel independently, but you have to find two colors only for each 8*2 block, so some color info will be lost. Now if you shift each line for every pixel and see which horizontal position loses the least amount of colors, that's the one you will keep. Bottom line: this reduces the "blockiness" of the images, and the only thing you lose is two characters on each side because of the 38 column mode. However, because of all the above, this mode is mostly (only?) suitable for still images. Think about it, even a simple scroller on top of the picture would be a problem, since you'd have to "cut" the character graphics every which way.
To write a game simply using any FLI mode would be good, I'm sure we've all though of this lots of times. The only problem is that it eats too much CPU power, and to write a really good game, we'd need LOTS of CPU power for the graphics (remember, no sprites!) It's not impossible, but very difficult.
