The Internet Archive has an interesting collection of historic software games that you can actually run on your modern computers. Of particular interst to me was Karateka, which I played the heck out of back in the day.
The Paperclip Factory game is a strangely compelling browser based time waster. You start out by clicking a button to manually “make” paper clips. After a while, you get enough money to afford to purchase different types of automation, then scale up to various computer systems and so forth.
Tigers On The Prowl was HPS’ 1996 computer game of WWII Eastern Front combat. A classic hex and counter game, it is available in an MS-DOS emulator on the Internet Archive.
Atomic Games’ World at War Stalingrad is available on the Internet Archives in a DOS Emulator. The game, co branded with Avalon Hill, dates to 1994, and is a classic hex and counter design.
The Internet Archive has an emulator for SSG’s MS-DOS game, Carriers At War. The 1992 game ha a number of Pacific Battles to fight out. I enjoyed this back in the day.
