I don't know how many members have had an opportunity to play FIFA's pro-clubs mode with their friends, but it's a blast. The idea is that you have your own player that you make an upgrade and play a role on your team. Using RTTS players, for example, would be cool to get to build a team with your friends. Each person could have a Pitcher and Position player that they build and upgrade in RTTS, then select them for their team, where they would add friends and design logos and uniforms like in diamond dynasty and build their organization. Then, each count could start 1-1 in a 3 or 5 inning game where you get to plug in your player on defense and hit in a lineup that only includes you and your friends (lineup wouldn't include computers who fill other defensive holes). Then, when your pitcher is in to pitch, you could throw, and your player who is in the field, could become a computer with your attributes for the time being. For example, if I make an Anomaly centerfielder and a CP, I could play centerfield for the first 4 innings, then, once my pitcher comes into throw, my centerfielder becomes a computer and I end up controlling my pitcher. As you and your friends play more games, and win more games you could be able to upgrade the players who are always controlled by a computer on defense and have them improve.
I've talked to a bunch of friends who are not even baseball fans, and they have said it would be worth the 60 bucks for MLB the Show just for this mode alone. Sony, I urge you to make strides to add this and grow the game we love to people so new to it.
