content: I will start off by saying I have not personally played this game. I don't really like chess so am not super excited to play. But my son really wanted this for Christmas. I was a little leary of getting it because we have had laser games that didn't work very well in the past and ended up being a waste of money. But there wasn't much he wanted for Christmas and the reviews on Amazon were good so I got it for him.He loves it! Him and my boyfriend have played numerous times since Christmas and they are both addicted to it. My boyfriend keeps begging me to play it with him when my son isn't around. The lasers are very strong and neither of them have complained about having any issue with it working.It also seems to be very fast play. I don't think it takes them more than 20 minutes to finish a game.And I love the fact that it isn't something that has to be plugged into a TV to play and it makes you think and strategize.
