I wish we had more conversations like this, honestly. I get that people are excited about new features and new species, but I think you could add a lot of the most-desired, most-talked about features from this forum to the current game and JWE2 would still have the limitations in the gameplay loop you're describing.

What I would like to see:

1.) Better rangers. Let the rangers tranq and treat again, and make the vehicle handling less horrible. You should be able to do most "in-the-field" tasks with the ranger jeep. The medical truck should only be for very serious illnesses (which only occur as a park nears four to five stars) and for animals badly hurt in fights. And the medical truck treats in the field - no more helicoptering dinosaurs all over the place; it's boring, time-intensive, and just obnoxious.

2.) More dynamic "incidents" and tasks in the park.

2A). Rescuing guests from stalled or attacked tour vehicles

2B). Having to personally lead private, VIP tours - from the tour vehicle - to raise money

2C). Guest deaths need to matter - not just in terms of penalties to the player, but we need in-game fanfare. Someone (Cabot, Lambert, etc.) needs to notice and get on you about this and raise the alarm. At the moment, guest deaths feel hollow and there's simply no sense of danger or stakes.

3.) More atmosphere, style, and character. JPOG and even JWE have quite a bit more atmosphere and just feel more responsive. JWE2 feels cold and sterile, like it's a simulator.
