I've posted a summary
here as well.
I'm in two minds about the new approach on Next Gen. I can appreciate the creativity, moving away from a linear story and making proper use of The City as something of an open world experience. It sounds as though Park players will be able to ignore the NBA side of things more easily than before, though the NBA experience is probably going to be very tied up in The City, which may not be to a lot of people's tastes. As always, there's a lot of stuff that sounds cool and creative on one hand, but also makes you wonder how much of a priority basketball actually was.
I have to say that the matchmaking options, while welcome, are slightly underwhelming. While they should improve Park play, I'm guessing The Rec and Pro-Am will still be a disorganised, toxic mess. Proper matchmaking was already years overdue, and it looks like it'll be another year before it's truly implemented in the online scene. I've been drifting away from MyCAREER and its connected experiences so it likely won't be an issue for me, but I want it to be as good as it can be for everyone else. I've spent a lot of time with those modes and know how fun they can be when they're good, and how much better they'd be if they made some sorely needed improvements. It's a step in the right direction, but again, it's lacking improvement for The Rec and Pro-Am.
Current Gen's approach is likewise creative, and I understand freshening things up with out of the box ideas and aesthetically pleasing and interesting locations. At the same time, it won't matter if the experience on the sticks doesn't improve. With no changes as far as matchmaking, and a questionable level of improvement compared to what's being promised for Next Gen, I'm not setting the bar high on that front.
All in all, there's some cool stuff here, but also a lot of stuff that's superfluous to the core experience of virtual basketball, be it single player or online multiplayer.
