This will probably take multiple years and multiple games to implement, but here’s what I would like to see:
I would love to see a more in depth RTTS. High school and then being drafted out of high school and deciding to go pro or not would be great. If not a college option would be great. Also, including more levels of the minor leagues would be great. Since the path to the majors would take some time, having a lite mode to RTTS would be great for players that do not have time to grind or just want to be in the show and not spend much time in the minors. I would also like to see more off the field aspects as well that include cut scenes, endorsement deals, and more interaction with your agent to request trades. In addition, if you are a higher ranked prospect in your teams farm system, there should be a greater chance that you get traded if the big club is trading at the deadline. I would like to see other things as well such as endorsement deals that determine what equipment you can wear to a degree or maybe you get a discount to buy the equipment. I kinda think that equipment should be separate from the auction store in the show. I love how you can go to the next game of a series without returning to the clubhouse menu but I think a cool feature to implement along with that one is to switch uniforms without having to go back to the clubhouse menu as well.
In Franchise, I would like to see the ability to start a franchise mode in any era of baseball from 1900-present. Include historical rules, rosters and stadiums, uniforms, logos, schedules and draft classes as well as CPU logic. (I love NBA 2k’s eras mode, but the cpu logic of eras mode is just like the modern game you see today.) I would also love to see being able to drop a RTTS player into any era as well. Improve trade logic. Put all time teams and classic teams in the game as well in play now modes and franchise.
In team designer, allow us to design more than just a home and road uniform. Allow us to design 1 or two alternate uniforms as well. Also stadium designer needs a touch up to allow for different field designs and foul territory layouts as well as seating arrangements.
Since MLB is having teams go back to wearing their team’s Jerseys in the all-star game, make sure it is in the game as well. Before I had a console to play MLB the Show, I played MLB perfect inning on my phone. If a game on your phone back in 2015-16 can get players in their individual team uniforms, then a console game should have that feature as well.
Include multiple commentary teams and presentations. To be honest, I liked the MLB Network presentation and when it was gone, it was a bummer.
Also, this really isn’t a big deal, but not every game that is the last game of a regular season series is a day game. There are night games that are the last game of the series. Include minor details such as the fact that the cubs always usually play on Fridays and Saturdays at 1:20. It would be cool to see a Sunday Night baseball presentation for the game which could be an MLB Network presentation. It would also be cool to have a presentation for Saturday night games as well.
This might be a crazy idea, but maybe let people create custom game scenarios in the game by partnering with Out of the Park Baseball. I feel like that would be cool as well.
