Je Cheon Dae Seong: BaeKkop Jap Neun Sa O Jeong

Simplified JRPG with arcade elements. Main gameplay is like in any other old JRPG - you're travelling as a group of 4 heroes across the global map, visiting cities & villages, talking with locals to get assigments, etc. During the battles, one of your heroes is teleported to a closed dungeon arena, where you must shoot all the enemies in order to complete the task and go to exit
