White areas are snow covered, yellow areas desert and dark grey areas are mountains. Trees, rocks and ruins are represented by green, brown and black dots respectively. The rest should be self evident.
These maps are only 80 x 60 tiles as thats the size of map I'm using to test the game. The maps in the final game will be much larger. Each tile takes up two bytes so a 1000 x 1000 sized map would take up two megabytes of system memory while the game is running. I think the final maps will be about that size but I might make them bigger depending on how much memory I use elsewhere.
I'm quite pleased with the roads. I wanted them to consist of lots of nice long straights. They seem to fit in with the road warrior theme nicely and hopefully combat along the roads will be similar to the wonderful arcade game "Spy Hunter".
