I know very little about the "Wizardry Empire" series, but since there are apparently Empire games for both GBC, PSX, PS2 and PSP I guess that says something about the Japanese affection for everything even remotely related to the "Wizardry" franchise. The graphical style is a bit more Anime than Medieval in "Empire" but the basic gameplay seem very similar to an early, pre-Bradley PC Wizardry game. The first person perspective dungeon exploration is certainly intact and the town menu looks closely modeled on the towns in Wizardry 1-3 (temple, inn, trading post, training grounds etc.).
