You'll be better off finding something else — anything else — on which to spend your $20. The Island of Dr. Frankenstein isn't worth your time or attention, and aside from the original concept and story, it doesn't have any redeeming factors.
There’s very little to enjoy here at any point during the experience at all. As you’ve read enough times already, the endless fetch quests don’t even remotely translate to entertainment.
I’m a gamer who regularly plays adventure games with at their core are nothing more than glorified fetch quests, but I just can’t bring myself to call this game an “adventure” because it isn’t an “adventure.” A better word to use is “job” because it is work to have to play this game.
