I'm giving them away!
Take a standard 2-player sporting game. Put the player in the roll of a coach, desperately trying to win. Make the athletes four-year olds. Just imagine it. Give detailed orders, to no effect! Each player has one piece ("The coach's kid") who understands the rules, but is still more interested in snack time. [Done right, with just a bare modicum of control, this could be fun].
And yes, my kids did well in T-Ball. Especially if by 'did well' you mean 'got snacks.' I'm the proud father of the youngest contract hold out, with a long list of demands.
I'll leave it to those of you who understand baseball to work on the T-Ball adaptation. (I like the idea of having individual player cards, ala PtP or Strato, but with stats like Snack Susceptibility, Attention Span, Cuteness, and Parent Aggression.
As for me, I think I'll design "Pee Wee Football Strategy." Just imagine -- Defense puts down a card. Offense calls out "Long Bomb", then the defending coach flips "Safety Blitz." Let's cross-reference:
"The safeties cross the line quickly, then get distracted into tackling each other. The left wide receiver goes racing down the sideline, only to trip and be hustled away crying by an overprotective parent. The other WR runs a quick slant at five yards. The QB's throw lands at the line of scrimmage. Several minutes later he is tackled. No gain."
Afterwards the coaches order pizza, just like real Pee Wee football!
