Welp. Surprisingly...that was a pretty fair review. What he said about MyCareer wasn't concerning (I KNEW it was going to be cheesy
) but what he said about the Park seems like a hassle if you aren't already used to being in parties with your friends before you play a game to coordinate.
Didn't like seeing that Curry two-hander. I know he can do that in real life, but he's never done it in game. They just need to fix dunk packages in general.
This all but confirms that yes you can PLAY games in MyGM. In fact, if you don't play the games, it seems like you don't get the other upgrades (either not as fast or not at all I think).
