20 MS-DOS games released in 1983 - in under 5 minutes

Hello and welcome to the second episode of evolution of MS-DOS gaming. We continue our journey in 1983. Games were still pretty simple and most of them were still either text based, monochrome or used (in best case) 4 color in CGA mode. But it was still obvious that the quality of the games reached another level (compared to games from 1982) - with games like Digger, Battlezone, Ultima II, Frogger and Donkey Kong. Games are, as always, presented in no particular order. Have fun and let us know in the comments if you think of any games we might have missed.
