Lost Ark promises to rival them all. This upcoming game by developer Smilegate is using the Unreal Engine 3 and a top-down isometric view to create a hack-and-slasher.
Steparu.com has a nice preview of Lost Ark, saying that it is a potential rival to Lineage Eternal. It has mounted combat and 18 playable characters, some of which are gender-locked. Lost Ark is planning on a 2015 beta, and sign-ups are on the Korean site. If you can't wait that long, you can get a video preview of it after the break.
