I want to get the fame bonus for seeing 1-million and 4-million tiles, but I'm not sure how many I've seen so far. Right now I'm just roaming around the map, but I'd like to know if I can stop now.
As taken from the WildShadow Forums:
Tiles count as "seen" if they are filled in on your minimap. The circle of "seen" tiles on your minimap has a radius of 16 tiles. You can do the math from there.
Otherwise, NO, you cannot see your current tile-seen count at all.
Use Muledump. It is easy to set up, but read the instructions carefully.
