What if the industrial espionage attempt that failed was not the only attempt? What if someone succeeded and figured out how to duplicate the process...mostly. To fill in gaps, they reverse engineered some of the process, and came up with something close.That is an interesting take. I like the idea of tokens for “deus ex machina” -style escapes.
But other worries I have are with the plot and the characters. All my players are familiar with the movies. So that raises the question where and when the campaign/adventure should take place. Do their characters replace the main cast of JP1? Or do we explore Isla Sorna from JP2? Should any of the original characters feature at all, or just the side characters? And how can I surprise the players with the plot, when they are all so familiar with it?
Now, with the (flawed) tech in the hands of someone with less ethics than money, a similar park gets opened elsewhere. China? Russia? Australia?
An actual man made island in the Middle East?
Only THEIR critters aren’t so much dinos with some amphibian DNA for controlling the reproductive cycle as real chimera. They don’t even correspond directly to the critters we think we know so much about. Why? Not only was the reverse engineered tech not quite right, those behind the whole scheme actually cut corners intentionally.
