Some of the answers are wrong. For example, it asks for the total amount of animals and plants in a specific area and the answer is 'biome' instead of 'population' (there is also 'community' with is what biome is in some definitions). Some questions do not have clear answer. There is also the 'cat flap' question that is supposed to be 'Isaac Newton' even though there is no proof of it and there was some Marshal dude and Duke Ercole d’Este that also invented it, neither of which are options. It is bad to have the main content of the game to be of low quality.

This mixture of RPG mechanics and trivia systems gives the game a unique identity because success often depends as much on knowledge as it does on combat decisions. Instead of relying entirely on grinding levels or mastering complicated battle systems, players …

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
