All the gameplay footage I've seen has suggested the following:
1: The art style is definitely Korean, and turns me off. I figure some Koreans are probably disgusted by American art conventions in American-made games, too. I just really dislike it, and after playing a bunch of Korean MMOs I've had enough experience with it that I'm just done.
2: The animations are sometimes very stilted and weird. Like they're posing action figures instead of moving people. And yes, a TON of games get this right, so it's not an unreasonable expectation.
3: The player housing is instanced inside housing-buildings, like Anarchy Online. That is, when you walk up to a building that can be a player house, you choose which interior to explore. There's a significant load period as the interior is populated with the player's decorations. This means you can't be the guy who owns a house and have a pie-throwing feud with the neighbor who lives in the house across the street. Instead six dozen people live in your house but in different dimensions or something.
4: All the player houses I've seen have been crammed with crap so they all look like hoarders. Don't worry about dying in the dungeon, they'll probably be discovered crushed under a pile of damp newspapers. I think this may be a player behavior though; I remember UO houses frequently looking like packrat nests.
5: Ugly sexism. The ladies are all teenagers in short puffy skirts, people can buy scantily clad slave-maid NPCs for their houses, etc. Few customization options for males but there's probably like 8 nipple sliders for females. I don't care that I'm exaggerating, I'm trying to convey the overall impression I get.
6: Low difficulty. Who are they catering to?
7: The grind! Again, one could argue that all MMOs have a grind, but many have good ways to conceal it, make it entertaining, give you options on how you do it, or minimize the headaches. Generally if the gameplay is super fun you won't notice the grind as much. That's not the case here.
8: Sure you can auto-path to the next town. But why is that an option? They saw a problem called "walking in this game is boring" and their answer was to still make you do it but let you macro it and go make a sandwich.
9: Poor polish. For example, when you're auto-walking along a road, you're following the same invisible path everyone else is. Which means you all run straight into each other and phase through like everyone's a ghost.
SO basically, they reneged on every promise I can find and they would need to change many fundamental parts of the game in order for me to consider it worth downloading and playing for free. I'd play it if they paid me $20 an hour but I might look for other work on my breaks.
