There is something called "mini games".
Those games are sometimes so small that you could send them per email, ...

Sometimes you just need an extra application to setup some options before you launch the main game. A4 is small enough.

Oh, do you remember MODEM or IPX support?... Yes, these things may be outdatet, but there are schools networks still using very ancient protocols on 10 MBit connections...

And ... NO! I would not permanently downgrade!
I would like to see it as an option to use it if I am in need to.

If I am not allowed to sell my older version - why should I not use it if it fits best to the problem?

Ok, I am not asking for myself...
