Microsoft Adventure

The Good
It was the first, writing is solid one.

The Bad
I'm trying to experience old games as they were, taking into account technical limitations of that era. Despite being made in 1981, Microsoft Adventure is not the best, what was possible in those times, from technical perspective. The game is using 40x25 text mode even if 80x25 was available on PC. IMO, it was not good decision as there's not lot of text on screen with minimum text decorations, thus reading it is a bit strain on the eyes. From that point of view, text adventure games which just came 1 year later on identical hardware (Zork, Infocom adventures) are much better in that regard.

Edit: so I found that it's possible to have 80x25 text mode in this game. I found that DOSBox-X can emulate MDA (IBM's Monochrome Display Adapter). If you boot the game with MDA emulation, voila, 80x25 is there, which is way better. 40x25 text mode is used with more common CGA, which is strange, as indeed CGA has 80x25 text mode as well (in the end even early PC-DOS 1.00 booted into that text CGA mode).

The Bottom Line
Important from historical perspective. One of the first games on IBM PC and very first text adventure on PC, when almost nothing else was available yet. But soon, it was superseded by much better entries.
