I'm mostly a franchise player but just clearing out space might be key right now. Oh the terraces, yes I can't wait for those too - I was just working on some habitat ponds this weekend and was wishing we had that already. It may end up being my favorite part of the update.I've mostly just made empty space for them (and cleared out some bad terraforming in the hopes that I can improve it with terraces), but it's also good reason to redo habitats. Of course, I'm in sandbox, and I don't know if you are, but I've just been fixing random things I feel could be renovated -- odd roofs, unrealistic exhibits, drab buildings.
I could just go through some of my newer zoos and finish some of the outside shells of buildings. That could hold me for a week
