When we were kids we played with as few as 3 per team. Self pitching, ghost runners (if you toss to 3rd base before the runner reaches 2nd it&#x27;s an out), etc<p>On the space side, we played where ever - you just needed a place to put down some bases or some trees that are relatively evenly spaced in 4 corners.<p>We made it more fun by playing with crappy tennis rackets and tennis balls we &quot;popped&quot;.<p>You&#x27;re right about &quot;pure&quot; baseball, but kids create their own ways to play games and baseball can be changed enough to be fun and fast paced.
