Where the heck did they come up with that number? That's even more arbitrary than 72 (which is at least divisible by 9. I just figured out why the chose that number for the nonsensical "screen dpi." You'd think that would have been far more obvious to a math geek).

Anyway, I shoot for 100px / square in my D&D 4e game, which I display to my face-to-face group on a HDTV. My maps are about 5-10 MB in jpeg format, and my 32-bit png tokens run to about 30k. That's a bit on the large side, really, but since I'm not having to transport the assets over the 'net it works out.
