Well, I maybe have overreacted. Yes, several projects based on the same IP is very likeable. But yes, some "inspiration" can come from other projects too. Flinstones is an IP I have quite an interest, so it catch my eye.
And you are right that we should give support to the project that has to most chances to go through Lego review. So that is why I am a little bit uncertain of which support.
The project I mentioned that I have supported is this one:
https://ideas.lego.com/projects/157569
As you can see the projects were created very closed to each other, a matter of days, so it is hard to some "inspiration" have crossed from one to another.
But both projects shares the number of minifigures, house and car (which is understandable since those are the most recognized features from the IP).
I liked the figures in the project I pointed more because somehow the renditions of Fred, Wilma, Barney and Betty look better. Fred and Betty look specially worse in the project you mentioned (I cannot stand its Fred). However, Pebbles and Bamm-Bamm look incredible better in the project you share. But ultimately, Minifigures design would be something that TLC would improve a lot.
The House looks way more complex in the project I looked however there is something in the simplicity of your project that fits well. The car is also up to debate.
In resume, which one do you think should gather our support?
Like I said, I liked Flintstones a lot, and I wish TLC would make a line based on the IP, like they did with Scooby-Doo, not only an Ideas set. A set based on the quarry (with the working dinos) would be really cool. And speaking of dinos, Dino the "dog" is missing from both projects!
Edited: I just saw that the Flintstones project I linked was created by ThomasW, the same guy from Observatory Mountain View which is currently in Lego Review phase. But he already submitted another Flintstones set (with only figures and the car) that expired without much support (
https://ideas.lego.com/projects/101800) which does not look too good for the success of the current one since the house is not its strongest point.
