I have a quick question on tile usage, more to do with aesthetics than anything technical.
There are two basic tilesets used for "paths" in FR/LG from what I can tell, basically these guys:
These are all the places that use the dark tiles on the left (I'm not counting places like Viridian City that obviously only use a few of the tiles because they're continuing from other routes):
Viridian Forest (but also has a bit of the light tiles, near the entrance/exit)
Cinnabar Island
Route 3, 9, 10, 11 (with a few light tiles), 24, 25 (but a bit of light near Bill's house)
Route 4 (half and half; mostly dark tiles by Mt. Moon, and light tiles by Cerulean)
And these are all the places that use the light tiles on the right:
Cerulean City
Vermilion City (but a bit of the dark tiles, in the place where the "new building" is going up.)
Fucshia City
Route 1, 2, 5, 6, 7, 8, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23,
Route 4 (half and half; mostly dark tiles by Mt. Moon, and light tiles by Cerulean)
So, what's the pattern to which tiles to use where? Obviously the light tiles are a lot more common, and it looks like mountainous/rocky areas almost invariably get dark tiles, but are there any other apparent rules? Especially on the dark tiles; it looks like the light tiles are default, so I'm wondering about dark tiles that don't conform to the "rocky area" rule.
Thanks for any advice/opinions.
