my boys have bought the Spore creatures game today, one of them has started off, but now the other boy wants a turn on the game.
my first has told him he's got to use the same spore as he will loose it.

is this true
or can they both have their own spore and continue play when they have taken in turns on the game

I would have thought that it is possible to use more than one, but having never played the DS version, i'm not sure
