If we are back on the map issue I'd like to post this:
Mercator ? Cylindrical projection? are you sure you're not talking about variants of the same thing?
The problem is not using a mercator map to "visualize" positions. The problem is to assume that actual distances are reproduced on mercator or similar projection. Do a test. Measure the distance between two meridians on the equator (on the game map). Measure the distance between the same meridians near the north pole. The game tool will give you the same distance while in reality as we approach the poles the distance must be shorter (and going to zero on the poles themselves). The map scale (for distance measurments) should not be the same for all latitudes.
BTW compass courses, bearings are accurate in mercator type projections.
P.S. the game map actually looks like a
Miller cylindrical projection which is a modified mercator projection (

If we're to cotninue bashing each other then my apologies for being OFF TOPIC......
