We build the games for different age groups, the order is.
Putt-Putt Freddi Fish, Pajama Sam, Spy Fox.
We found that once kids hit 8 (or so), they stop playing the same game over and over. 5 or 6 year olds would play Putt-Putt everyday from beginning to end and not think anything of it. Once kids hit 8, they stopped doing that and we didn’t make adventure game for 8+ due to the scope needing to be much larger. Games like Backyard Baseball, etc, hit kids older than 8.
