Is there another name for this game?
I don't find any data of it on the pc engine software bible.
Is it really good?
No, it's not
really good. But still good.
For as long as it lasts its cool enough, although part of the appeal is it being one of the only of it's kind for PCE/Turbo.
Its fun to play through, but nothing special. Pretty much middle of the road.
If it went for $30 I'd say pick it up to play if you're a casual Turbo fan.
Otherwise if you just want to play it, are not buying it as a collectible and are not a crazed Turbo fan who's impressed by anything put on the system, you should at least try an iso or borrow the game before buying an original at such high prices.
Especially if you don't own every sub-$100 great PCE game already.
Because you can pick up 10 - 20 of the greatest RPG's of all time which are PCE for the same price or less.
