Football for hours was our go to. Summer in particular was great, home from school, couple of hours playing, tea then out again until all the mums started shouting you in hours later. Not sure that happens anymore. People blame FIFA games and the like but I get the sense people are just far less willing to let their kids out for hours now and either the risk are greater or people are more aware of them. 25-30 years ago feels like a different world.

Rounders and kerby were other favourites. Burn jumps, tarzan swings, the spectacularly un PC 'Japs and Commandos' all get honourable mentions too. As we got a bit braver and more rebellious tap door run was also hours of fun (until you got caught and your dad got told).
