Realistic Dark Rides... more dark rides... and dozens of dark rides please. If they cannot support real-time ray tracing so that buildings will be properly lit inside, they need to do a lot better than having to build rides underground to make scenes pitch black. We need to be able to make realistic dark rides. Possibly with a wall set that makes objects within their bounds pitch black and require them to be lit (PLLLLEEEEAAASE FRONTIER).
Realism... PC1 is cartoony but that works well with the look and feel of the game. However, there are features that should have made it into the game. Touches of realism inspired by the TMT such as wheelchairs, strollers, turnstyles, food carts, and so on and to the immersion making you fill like you are at a real theme park.
Fixed Motion Rides, Parades, Custom-Walkthrough Attractions, and Auditoriums... Custom stunt shows, 3D attractions, motion simulators, and horror mazes are missing from PC1. It is possible to do these things with PC but they are only facades (for the most part). Custom auditoriums and walk-thoughs are much better. Fireworks and water shows are a great features in PC1 especially when paired with vista points.
Rigging... adding scenery to moving rigs creates a new possibility for set pieces. We can now stack scenery how we'd like but imagine if this could be animated using bone animation and other types of rigging. This would allow us to create our own characters and themes that are actually animated!
Embedding... audio, images, video, and TMT items into park files and blueprints so that links to 3rd party assets do not have to be downloaded from the steam workshop.
Improve Queues... zig zag queues that only become occupied when guest limits have been exceeded for certain areas, multi-station ride queues get split into multiple queues like they do in real life. As an added bonus, staff member could open the extended queue area letting more guests in.
Pre-show Sections... show buildings and pre-show sections that take in groups of guests from a queue would be awesome. This would work well with smarter queues.
Better TMT... allow for video textures, embedded audio/video, and possibly some JavaScript. This is a bit out of the box but hey it's an idea.
Higher Performance and Optimization... larger parks and blueprints that take up less of a memory footprint and perform exceptionally.
Migrate PC1... Even if we have to pay for it in single DLC... all current DLCs should be in PC2. We have gotten used to having these pieces in the game... DON'T WATER PC2 DOWN. There are still many possibilities for future content. We will continue to support the franchise if the franchise continues to listen to us.
Fix Horror Heights... Continuity upon triggers are one thing but the Horror Heights having steps and a beginning rotation animation is a bit annoying... This should have been a track ride. It isn't all that bad but could use some improvement. Personally, I think this is an underused ride in the game.
Fix Motion Track Rides... it's not that they are broken but rather incomplete. The system of setting rotation, pitch, and so on, via track pieces is dated now. The track editor should allow for motion in a fixed or moving position, change in velocity (speed and direction meaning going backwards). In fact, trackless powered motion rides should not even have a track but rather areas in which the ride vehicle can move. Then we could freely sequence ride vehicles stand-alone or in groups greater than one vehicle. A ride vehicle can be motion controlled even if it is not moving along the virtual track. The Re-Motion and Hunstman rides are somewhat limited to linear motion for no other reason than the developers didn't raise the bar.
Custom Billboards on Everything... custom ride vehicle skins, staff attire, and souvenirs using billboards.
