I think the "But" can be removed here.

How about saying "(such as prboom-plus)" ?  That way people know what to 
install.

Otherwise, looks good!  I booted it up and it worked great.  Lost 15
minutes into shooting up zombified soldiers...

One comment about the submission: maybe it would be better in the future
to post a patch formatted using git format-patch?  It would be easier to
apply and push.

But it looks like you have commit access, so with the couple of
description nits adjusted, I think it's okay to push!  Nice work!

Freedoooooooom!
