No need to be private. I like to air my grudges publicly. :)
In 1990 I wrote a shareware X-windows game, Xasteroids, which has been very
successful. I've received hundreds of email letters thanking me or requesting
help compiling it. I've had it republished on 2 CD-ROMs, with the shareware
notice. One of these, in Japan, was a run of around 80,000 copies.
A descendant of my game (reworked by someone else) is in the Slackware Linux
release, and my version is (I'm told) in the Debian Linux release. It was going
to be in the Sun Book of Games on CD-ROM, but was dropped for legal reasons.
(Imagine that. :) *
I asked $5 for the game. I've had 2 or 3 people pay the $5, plus one guy
who gave me around $40 to put it on a CD. Prentice-Hall was going to pay
$100 to reprint it before they dropped it.
Interest peaks when it finds its way to a new major site, like
export.lcs.mit.edu or the X games source newsgroup, but letters keep
trickling in now. The registrations, I think, came within about a year
of distributing it, but the requests to redistribute it bundled with other
software did not begin until around 1993.
I didn't provide any incentive to register -- no goodies, hints, or secrets.

They dropped a lot of games for legal reasons, and then they asked
more of the authors to change the name of the games for legal reasons.
Some of these authors (2 out of 2, as far as I know) answered that it wasn't
worth $100 to rework their games to change the name -- something I find hard
to imagine, but, hey.)
