MET is the clear choice WITHOUT kids. No way in hell would I recommend MET for kids though. Not even sure where to begin on that one. Prob electrocuting someone and his eye balls popping out..... The wife is going to love that one!
My kids BY FAR loved GB the best. GB would be my answer no question. They love slimmer and who doesn't love that theme? SW is such a complete mess of a game (pro being a trash can on fire/ prem is the only way to go if you want to torture yourself). GB code does get stale though but you should be able to enjoy your time with it.
