I'd been thinking of making a 2d top-down game and looking for legal sprites. I ran across CraftPix
There are some free sprites, but the membership looks tantalizing (all access). The monthly $15 is a little out there, but $36 yearly fee seems ok. There are no royalty fees even if subscription is cancelled.
I'm not making good enough games to even think I would need $$ sprites ;-)
I'll bookmark it, might come in handy one day.
