MU Legend

The game entered closed beta for western audience so I gave it a spin last night, looks interesting.

first impression is pretty much 'MMO D3', even the skill system is very similar
controls are the usual affair for an arpg, the character is fairly responsive
animations and graphics are decent enough but not amazing, effects are moderately flashy
performance was good except in town with 50+ people on screen at the same time, I tried some dungeon runs in a 5 man party (automatching system works nicely) and it was fine
UI is among the best I ever used in an online game, very clean and straightforward
it has some very neat touches like setting transparency level for other players' effects to reduce screen clutter
seems to be worth a try but I got no idea about the payment model or the amount of p2w, and it's kind of a big deal for the final verdict

There's a detailed review here from korean closed beta, no idea what changed since
