Home of the Underdogs (HOTU) is a software information archive founded by Sarinee Achavanuntakul in September 1998, and has grown to be one of the largest abandonware sites on the Internet. At first it was hosted on free homepage providers like Tripod, but later moved onto its own server.

It offers reviews for over 5,300 video games, as well as providing downloads and manuals for many games that are no longer available for purchase. Most games available on the site are for the PC (DOS and Microsoft Windows), but the site also contains a section with games for other platforms; these latter games are usually in formats that are compatible with emulators. The site also has scans of 33 gamebook series, many of them complete.

This site has a massive selection of games free to download. Many of the old classics are here and many newer freeware releases as well. If you liked Panzer General and games of that genre you should check it out. Also many adventure, RPG and strategy games. No spyware or adware with the downloads. It's a lttle slow but aside from that HOTU is a fantastic site.
