It's really that bad?
I find this approach somewhat refreshing. The rules are the same but the vibe is certainly not.
Fake Artist already influenced creation of some other games. Perhaps Spyfall was invented independently, but Gooseberry/Chameleon acknowledges it as inspiration. Sunken Saylor is certainly closest to the original but it is generally very simple concept.
While ruleset-wise both games are basically the same, Sunken Saylor is provided with story card while you have to come up with own themes in Fake Artist. Anyone who played both implementations of Rikki's design (Gooseberry and Chameleon) knows that it can make difference.
While it is much easier to think up on word in Fake Artist than prepare board of sixteen words in Gooseberry, one still has to make it oneself. I've seen people struggle with it.
Sunken Sailor is ready to play without this preparating stage out of the box. It fits mass market game better. The possibilities are much more limited but this still could be better solution for some groups. And it's not only the words - while not affecting the gameplay, I find the story aspect of presentating the word to every player very clever.
When I think about it, it's not only aestethic and fluff too. In Fake Artist there is a Question Maker who not only chooses the word but also works with Fake Artist to accomplish common goal. Sunken Sailor on the other hand stand completely on his own. This is small rules difference that makes the game similar to Spyfall and Chameleon in that matter.
That said, I will of course not buy it. I don't need similar game that don't come with a new interesting twist (and I have all of there mentioned games). I don't think that such simple party game should come in wooden box. I don't like swearwords in game that would work perfectly with family and children otherwise. I can't even buy it, because it is only sold in Target, where I don't have access to, and I also don't like such exclusivity.
I like Oink Games, original Jun's is still better for me and I would prefer the game to acknowledge it's influences, but frankly it is only the last straw. As Dizz said, you can't protect game mechanics and you shouldn't call it theft. For me it is better if designers can freely derive from other's work.
a higher quality production...I would say that Fake Artist has higher quality. It has unique design with overall integrity and attention to details. It's just Oink game. Components are also as good as they can be.
Sunken Sailor looks like self-published game that one could make on their own from easy available materials. It's surprising for me that cards have rounded corners because it doesn't fit my overall impression.
