I would love to see a water park add-on put into this game. It would be everything to me to see guests going down awesome water-slides, or to see them have fun in a wave pool, or relaxing in a beautiful hot tub area. I miss those things SO much from roller coaster tycoon 3. Or how about an aquarium like there was in Roller Coaster Tycoon 3. Seeing people observing and getting to observe myself in first person would be everything. Or to make it easier for Frontier, how about just giving us more aquatic animatronics like swimming fish and an octopus, or maybe giant tentacles coming out of a dark cave, or a crab moving around, or an eel coming out of an opening. We already have the underwater bubbles and glass in the game, so that would work perfectly. To add to that effects give us some underwater foliage like coral reefs, sea weed, etc.
