In the current version of the game, all of these things do happen. However, they happen automatically, based on the feuds that you create.
In future updates, you'll be given more control over these, so you can decide what happens and when.
Yes! All three stats change - up and down - during the course of a game.
Draw value changes depending on your booking, so it is possible to develop top stars from complete unknowns.
Ability and Hardcore stats grow while wrestlers are young and improving. They slowly decrease as the wrestlers get older.
In Promotion Wars, the game rewards you with TV deals when you have been performing consistently well for a long period of time. TV deals mean more money, and bigger name wrestlers will want to sign with you.
From having no TV at all, you first progress to a Local TV deal.
From a Local TV deal, you progress to a Regional TV deal.
Finally, from a Regional TV deal you progress to a National TV deal. At that point, you are no longer considered an indie and you will have the weekly viewership of your TV show reported to you.
On the Weekly Shows screen, you will see an indicator of when you're getting close to a TV deal. Once you have interest, it's important to keep your Promotion Momentum consistently over 80%.
In addition to gaining TV deals, you can also gain Pay-Per-View, which allows you to make more money from your Big Shows and find out how many people order them.
The screen has a default, fixed size.
You can set your Secondary shows to be Auto-Booked via the Options screen.
Currently there is no option to switch off or delete a show, however, for players that don't want to book the Secondary shows, these can be Auto-Booked.
