Atari Anthology - PS2 - Flag Capture
Gameplay from Flag Capture. Includes a go on each one player variation.
This came out in 1978. It's a grid based puzzler, where you guide your stick figure pirate around the blocks searching for a flag. Each block contains a clue for the flag's location, or a bomb if you're unlucky, which sends you back to the start. You have seventy five seconds to find as many flags as you can. There are three gameplay variations, one with a static flag and two with moving flags. The difficulty setting doesn't affect gameplay in one player mode.
There isn't much to this, but it might be better in the two player variations, where you compete for flags against an opponent.
