Right now when you spectate a peep, it's relatively boring, because it's slow and it doesn't join many rides.
Since RCT3 I always dreamed of being able to walk around my park as if i'm a visitor. How about having the ability to spectate a peep and then control him via WASD or maybe Arrow Keys. Shouldn't be hard to program or implement (don't know if there's anyone beside me wanting this feature).
