If you can get ahold of an older PC, you should take a look at the stuff made by Future Crew, particularly their stuff that won the Assembly conventions. Some absolutely amazing stuff, especially considering what it ran on.
They also created one of the best MOD-tracking programs ever developed for PC, and subsequently set the standard for which all other PC tracking programs were judged against for years. Most of their stuff needs to be run in DOS however, and doesn't do too well with anything post Win98SE.
