If you want a basketball sim, go elsewhere. If you want a fun basketball-themed game, you're at the right spot!
First, graphics are pretty good for the portable console. It doesn't match with the two rivals, but framerate doesn't suffer a bit. The only issue might be gameplay, as NBA 10 is an arcade-style basketball game, with fast action and acrobatic moves. In fact, you don't need any technique or game plan to play NBA 10, just enter the court and do as you please. That's why there are many fouls in a game. Totally unrealistic gameplay, but it's fun.
But what makes this game a great "on the go" entertainment are the minigames: Pinball, brick destroying, dodgeball (new for this year!), and many, many others! All these games only take minutes to play and they are really addictive.
Well, I haven't much to say about NBA 10 other than it's a really fun game for almost anyone, but basketball aficionados should see elsewhere for realism.
