This game is INCREDIBLE! While I am dismayed at some of the cut content (extra levels and features; WHY CAN'T WE GET A FINISHED PRODUCT, LUCASARTS?) the gameplay is better than the first. However, as a note to concerned parents: if a child is playing through as a male character and has the option of practicing 'Echani Dueling' in the cargo hold of the Ebon Hawk with the Handmaiden, you may want to step in. Both characters (Male character and female Handmaiden) are automatically stripped down to underwear, which, in Handmaiden's case, is a two-piece. Be wary if younger kids are playing it.
Also, watch out for particularly nasty mods (such as nudity and revealing clothing mods) on the PC version. There can be some seriously immature modders out there who would love to see all in-game females naked, so be careful if your child downloads mods.
Moral dilemmas can be interesting tests of your child's mindset, as well. Check their light or dark side alignment once and a while, or watch them play. Don't automatically get mad if they're dark side, just be careful if they start exhibiting...unruly behaviors.
btw, why are you guys rating this 'on for age 2'? it's definitely good for tweens and up, not anything below that.
