This is the best asset pack I've ever used (My game made using it is here if you care. Full release coming soon) and I mean that with no exaggeration.
It's easy on the eyes, includes UI, tiles, icons and TONS of sprites. This rivals assets I've payed money for, both in ease of use and in how expansive it is. I've been working with these assets for six months now and there are still things I haven't implemented or seen.
The characters have tons of personality. Even the random villagers. There are sprites for every character and class you could possibly think of. Seriously. If you want to make a retro RPG, do not pass this one over.
