So far, we've seen that Nexon KR is fully utilizing their 1024 x 768 resolution. The Mechanic's FSAoE is absolutely huge and covers the entire screen. The Lionheart boss in the most recent number of patches is also extremely large. I think it goes without saying that they want to fully utilize the benefits of the increased resolution.
So, what else would you like to see them do with a larger resolution? What other things can Maplestory do once we have a larger game resolution that it couldn't do before?
