After reading this I really really hope we also get the option to play with expeditions + fossil extraction and research on in sandbox as well because a challenge mode with a limit on how many species I can have in my park really doesn't sound appealing to me more like a one time have to play to get those skins thing and that's it.
JWE challenge was pretty much perfect for the way I love to play these games (though the contracts are annoying and the rating system feels rather unbalanced) with a sense of progression while you build up your park from scratch. So it would be really amazing if we could decide whether or not we want to dig up and extract fossils and do research in our sandbox parks as well, so we can have that progression there as well but without all the limiting restrictions challenge seems to put on the players. Sandbox is supposed to be the mode we can tailor to our prefered playstyle after all and being able to do research and get DNA from fossils before you can breed dinosaurs is a huge, integral part of the game that not everyone wants to have fully completed right from the get go, especially when you're not just a builder but want to play with the management side of the game on as well.
