I whould help with that but too many people doing the tile sets and ya could start seeing too big of differences, mind ya most games of the 16/early 32 bit era had maybe 15 max (alot are reused)
You could do them all? Then there definitely won't be too many people! :D But seriously, it's only me working on
everything right now.
And yeah, really don't need many different tilesets; just enough stuff in them to be able to make different areas look unique. Just like small details like different trees/flowers/etc for a forest while stuff like the grass/water is the same, or different decorations for castles/dungeons while the walls/floors are the same. :I
