The Wizardry games, as far as I know them, don't have much of a story. Sure, there's a setting, some talk and a reason why you go into the dungeon, but from then on it's just "Yeah go to the bottom of the dungeon and slay that guy". So it's a dungeon crawl, a hack & slash.
I'm not sure how complex these later Wizardry games get, but if it's on the level of other JRPGs, then I don't see why you would play this. The most tactically sophisticated thing you'll see in a JRPG is something along the lines of "Oh, it's an ice monster, let's use fire spells!"
In the 80s that might have been adequate, but for a game that has no real story, I'd rather have a bit more depth.
Otherwise, games like these are for people who enjoy playing a game where they kill kobolds for 2 hours and then being overly happy and excited because their fighters HP is now 60 instead of 25 and his AC improved by 4 with the new found plate mail, whereas others would have seen this as 2 wasted hours.
