Depends on what you're after. In terms of mechanics it's a completely different game, but lore wise a phenomenal amount is tied in to GW1. It's almost fan service: the game.
I want to create a spiritual successor to this but I'm only a dev, and not an artist. It's really killing me. I want to make a game like this before I die, but it's looking unlikely.
Yeah, really the only word out of place in the headline was "Aztec". All the rest could have applied to GW.
Fun fact: In the early days (I think the first 6 months or so) of GW there were some item attribute modifiers that I think allowed for going as low as 5 hp, making the character basically invincible, as all damage was rounded down.
