luckily he's almost a toddler and can probably fight it off :-)

well that sucks; i'll just keep waiting i suppose, thanks.

i dont want to stray too off-topic; i know there is much more to a
game than D3D, but in the brief research i did, it seemed much closer
than you've hinted.  the guy even threw up a patch for wine to use the
tracker shortly after IIRC.  all in all, wine was still required of
course; i didn't see any indication of a VM/etc. but i see how it
could be used for that as well.

will have to look into it further i suppose; i just know several
people who do not bother with Linux for this exact reason, so it
appeared a solid move.
