Abandonware DOS title

The best underrated underdog games

In order to be an underdog, a game has to be "not well known" to the public (not now, nor at the time of its release) or underrated, but worth mentioning and playing for some reason. There are plenty of games that won the love of gamers against all odds; some of them even had a cult following. By the way, this keyword pays tribute to Sarinee Achavanuntakul, the owner of the first version of Home of the Underdogs, the site that started and popularized the abandonware concept.
