Personally, I liked it. Some parts of the story seemed either rushed or like they came out of nowhere, but I felt like the gameplay was fairly solid. I liked the characters, even if they might not feel as memorable as in the first games.

The one thing that might make or break the game for you is that there is a LOT of driving. The planets you explore are pretty massive and have their own feel and dangers about them. It's really important that you have the vehicle around because it helps to protect you from environmental damage from hostile climates. I personally found that a little annoying.

Otherwise, fairly solid game. I'd give it a shot.
