The last version of DOOM also had MIDI music, and it's not crappy at all. It was moody, scary and perfectly suited for the games that DOOM and DOOM II are. The Hexen II MIDI's also perfectly fit in the gameworld, and do not sound crappy at all. Maybe if you started gaming around the year 2000, you might think MIDI sounds shitty, but to me it's pure love from a time when most games were made with love, and not a wallet.
