OH yes I forgot to add these gems:

Makes flying through rings fun like never before. A modern marvel of level design and enemy AI

A great no rules racing game (yes I have played it, before it became famous, we got it for three dollars at a salvation army thrift store)

You thought shooting soldiers was fun!? Well you ain't seen nothin till you've poked them with sponges and cleaned their wounds!
And yes, I have either ownde or played these games at one point or another.
