Classic DOS games
Before the age of blockbuster titles created by crowds of programmers, level designers, visual artists and musicians, there were small companies that struggled to publish games on time.
Imagine a time when video games were designed by one or two people at most. A game could fit a floppy disk (do you even know what a floppy disk is?) and you had to actually go in a shop and buy something tangible, no downloads, no Internet (at least not the Internet we know today).
In those years, before Windows modern systems, game companies developed some of the best games ever made for a Personal Computer. That's what DOS classics are. Enjoy!
