My group usually uses a standard 1 inch grid chessex battlemat for combat but awhile ago I picked up a much smaller grid one, each square is 1/4 the size of the other (1/4' x 1/4' or about .6cm x .6cm for those in not in the US).
I really want to use this new mat for games since I can have much larger distances for encounters, our current one would only have about a 30 meter range since we use one square equal to 1 meter. It really sucks when just starting encounters many gun's are already at half range, and I don't want to use a tape measure if I don't have to......"so you guys are here on the table, and over on the computer is a sniper, over in the kitchen you see a building" would get annoying.
The biggest problem is finding mini's to use on such a small map, we currently just use the random prepainted mini's from dnd and starwars (we have a huge box of random ones from when me and a friend used to play) but they are obviously 4 times as big as needed.
So basicly I need something with enough variety to represent characters and mobs that are 1/4' x 1/4' or smaller, they don't need to be detailed, just something with enough variety to tell apart, or even some little ones of different colors. Little things I could put numbers on would work too for enemies.
Sorry I just spent the better part of yesterday looking online but coundn't find anything but I realized I have a good source of info/suggestions here.
We already thought of just increasing the scale of the squares on the normal grid but it then gets complicated remembering how far each player was from each other ect. for when an area of effect comes into play.
