First of all, as I always say: THANK YOU!!! For making my favorite game, and improving it all the time.
I was thinking how to make this game even more awesome for futures versions. One idea i had was to see press coments before and after the matches, or be able to read newspaper headlines after important matches, as for example Grand Slams Finals, being the favorite before a big tournament, etc. Or be able to answer question for the press, and depending on our answer our reputation with the sponsors and the audience will raise or fall.
Also would be pretty cool to see how popular is our player with the fans.
I don´t know if this ideas are possible o simple to make, but i think it can make the game feel even more real.
I hope you find this useful!
