Depends on the person. It’s very “old school” in it’s gameplay, and very hard and punishing, grindy, has perma-death, etc.
I’d think most modern gamers would hate it, but I personally like wizardry to games (though it helps that I’m old enough to have played older versions). If you like old school d&d, it’s very much in the same vein. The remake linked here is pretty good, I already own it from early access.
That was changed a while back, the current restrictions are you can only have as many people playing any given game as you have copies in your current sharing library
