if you run the free or lite version of anything you normally have to put up with some c**p or another, like 30 second count down till the program starts, so this sounds like a good idea.
just dont let them know that you know they are pirates, they might think its all part and parcel of the game and accept it
or
tell them that you know that they are using a pirate copy and that if they had a legit copy they would cut out 90% of this stuff
the game that had pirate copies kicked out without warning just gave people the impression the game was flawed even though it only affected the pirate edition (the largest section of players)
other options
(game specific)
level capping
more chance of your loot being stolen in your sleep
treat them like unregistered shareware games
treat them like unregistered shareware games
and
treat them like unregistered shareware games
and if that fails
treat them like unregistered shareware games ;)
