CAP Event Toggles
With events, you could make it so you may change the Park up by doing something, such as grinding a rail or wallplanting a park piece, resulting in draining a pool of water, or opening up a secret panel allowing others to explore the level more.
Does this suggestion exist in THPS1/THPS2?
If no: please provide reasoning on why it should exist in the THPS 1+2 game.
No, neither did it make it in later games, but it would really be a neat feature that adds replayability to the game
