Get some 6 year olds to play games like that and review them not some Zelda , Halo loving hippy.
When my son was 6/7/8 he loved the blocky Pc game Lego builder and other similar games even though to me they were so boring.
Reviewers should unerstand that their criteria for a fun game isn't necessarily the same as everyone elses, especially when reviewing a game not aimed at them!
