It's an ok game if you love basketball and old school sim games....I love both, and I enjoy this game, but would probably give it a 3/5.
Still, a lot could be improved to make this a great game, in my opinion:
The load times are incredibly long.
The game gives you VERY little control unless you want to coach during the games, I, personally, would rather set up rotations, offensive/defensive settings, etc. and let a computer coach run the game. Instead, you can sim games, but you have no control at all over the depth chart, offense/defense used, etc. Like I said, I want to be the GM, but don't want to do quite s much coaching.
There's not really any scouting. This would be an obvious and great addition. In signing International players it would be great to find diamonds in the rough/find overrated guys on the decline. Instead you just see their ratings, which is slightly boring, and also unrealistic.
It's a good game. It's interesting trying to build teams in different countries and leagues around the world. But, it could be a great game, and, right now, it doesn't fit that bill.
