I didn't see this anywhere on here, but saw a few elsewhere. I just wanted to throw out a few ideas that came to mind before I forgot while I played over the holidays. These are just things I noticed and thought of. It doesn't mean they are feasible.
Camera Angles - I would love to be able to choose the camera angle for the shows. Meaning if I wanted a higher camera angle, or up close like an Indy Show. Or even change the angle completely like what RoH does so you can see the entrance way behind the ring.
Custom/Old Themes - I'd love for them to be able to add custom themes again. On PS4 It could be integrated with Spotify. I use PC So this is an option on there anyways.
GM Mode - Same as every year. I get very easily distracted playing universe mode and just customize when I want, how I want and can never truly just play. I spend more time changing things than playing. I'd like to see a GM Mode, where you have to choose a brand, with a budget and manager the entire show and compete vs others online or CPU run brands for ratings, superstars etc.
Bi-Annually - A new game every year is too much, I think bi-annually games with DLC throughout the year, whether paid or free would be a nice way to keep things fresh.
WCW Thunder Arena - Just a personal fav I'd like to see in game and be able to do a full on WCW Universe.
Championships - Not a big deal, but I noticed that the ECW TV Title and WWE Light Heavyweight Titles were removed this year.
Call Letters for Championships/Brands - I'd like to be able to create a championship and choose call letters for it, or for the brand. All you need to do is have Jojo etc record each letter and then we can choose the letters, TNA or NWA etc so they actually say it. Not just choosing from the default list.
Match Types - More match types, like Inferno, 3 Stages of Hell to name a few.
These are just a few things I wanted to throw out there while it was fresh on my mind. First day back to work after the holidays and it's slow, so now was the perfect time to do this.
