A very long time ago I created a site called "Play Free Games".
It has a large number of online games that I wrote. Some of them are good, and to be blunt some of them are completely pants.
That said, the lamest of them all, "Beaver Long Jump" will always have a special place in my heart.
The best one is the "World Cup Soccer Game", which I'm pleased to say is in no way affiliated to or associated with the FIFA World Cup.
