i think they are suitable for everyone!
u need a lot of time though!
maybe not for the young because they easliy get boared and may not understand the icons and stuff ^_^
my tamagotchi turned into a tama that is not listed!
he looks like a pumpkin shape and his sides are black! he has L shaped legs and a stalk at the top of his head that twirls around!
if you know what happened please tell me! i have 2 and they both turned into this pumpkin tama! ^_^ :D ;)
i think the aqua pets were targeting youger childen.
it is less complicated than a tamagotchi because there is only two things!they are cute to look at so just take the batteries out!
