Parents will probably want to skip this game unless the child receiving it is already a Star Wars fan. It can be quite slow and boring at times, and I'm sure the technical issues and overall poor appearance of the game won't impress anyone who doesn't already know their Han from their Chewie. The violence level in the game is about the same level of the films; droids explode when hit and most enemies simply fall down after taking a few lightsaber swipes. If you let them watch the movies, you can let them play the game.
Star Wars nuts will buy the game no matter what I say, and there's much to obsess over if the mythos of the Force is something that the prospective player finds interesting. If you can look past all the technical rough edges, there are a lot of cool Jedi moments, though the game is a carbon copy of the first Knights in almost every way. If you want more of the first game and don't need any big steps forward, this is your ticket.
Deaf and Hard of Hearing gamers will be fine since the game offers full text accompanying all dialogue. There are no significant audio cues.
