Hi, I'm looking for maps to test my pathfinding algorithm (and compare its speed to other algorithms). I'm looking for the tests to be as realistic as possible for games, so I prefer running not only on random maps I generated but also on maps from computer games. I am looking for open source games that have simple 2D grid formats that I can use for testing (or any other such maps that are available somewhere). Any help will be appreciated. Thanks in advance.
