"Big kids" play the TCG too. Although both the TCG and TFG may be viewed as childrens games, mainly because they are based on Pokemon, they can be played by anyone that has an interest. As far as the TFG goes, I think it will still be more geared to children with simple game mechanics and the ability to learn to play and play the game with ease, but adults or older children will have the ability to make more complex teams and put more thought into their moves. Whenever OP for this starts, that is IF OP for this starts, it seems that chess clocks would be a very appropriate time keeping device.
