All the more reason to hold off on buying (or get it as a gift, I guess), in my opinion. Hamill and Conroy not being involved is a bit displeasing, but I can handle it with the characters being "younger." What will be the real problem is if the story sucks.
The combat will be the combat. Same as in the last two games. And that's solid, but if that was all I wanted, I'd just keep playing the first one doing nothing but the challenges. I like the story. That's what I'm in it for.
