Hey there Silvex5, sorry to disappoint you, but loads of people have tried making petitions, it just wouldn't work.I dunno about MyDinos tbh.Yet I doubt Spineworld will be brought back by its developers(Playdo AB if you don't know'em yet) not because of people wanting it or not but because:
1-The developers currently lack interest in the whole game and have sold the files to a Chinese company(name unknown)
2-Due to the spectacular graphics and music the game had the company couldn't pay anymore which makes them unable to buy the files from the Chinese company.
3-The Chinese company isn't willing to sell or host the game.
So, I doubt anyone from the official company will bring back Spineworld for their reasons that I see logical(I'm not taking Playdo's side)
If you want you're welcomed to help me in recreating the game and everything.And you can see what I've done so far here:

Sorry if I seemed mean or cruel, but that's the truth, petitions would neither give Playdo AB money nor would it convince the Chinese company to host or sell the files.
Have a good day. -Sanji
