Wizardry was pretty much the first D&D based computer game, using most the mechanics and even featuring cartoons by the DMG guy, McClean (sp?). They were party based dungeon crawlers though by the time Wizardry 6 came along, they were more like the Might & Magic games.
Wizardry games pretty much died out in the West, both officially (the Wizardry brand and Sir Tech) and unofficially but they were kept alive in Japan all through the years.
This game dates from the PS3 era, but was ported and update a bit for a Western release on PC, at both Steam and Good Old Games. Definitely Japanese, with the art, but they are more like the dungeon crawlers of Wizardry 1 to 3, than the later ones (and the sort of weird 4 and 5).
In any case, it's a budget release, $15, with a 10% discount at either site.
