Yeah, and every game you had to set the IRQ and DMA.
Ugh! Yeah that was a greaaat fun every time. Also editing your config.sys to get the last few bits of free RAM you needed to get that new game running. Or fun error messages like not enough HIMEM...good times.
There were several DOS games I couldn't run due to various problems. Mainly ones from the Dark Eye Northland Trilogy and one game called The Druid Circle (or something like that). Later on I was never able to get Orion Burger to work which was on Win95 I think.
But in the times of DOSBOX all of this has gotten much much better so I'm now replaying some of those games.
Later on the main source of problems were various copy protection systems, mostly Starforce and to a lesser degree Securom. The Fall - Last Days of Gaia used Starforce and produced a bluescreen while booting Windows every single time after I installed the game. That was really awesome, especially because the game was cracked shortly after release. You really feel valued as a customer this way! At some point they released a patch for Starforce that fixed this, but if you weren't able to get back to a working system...tough luck. X3 Reunion had the same problems with Starforce and only started working after they released a official patch that removed it (could also have been X3 Terran Conflict, I'm not sure which of the two). Overlord 2 also had some problems due to Securom which were fixed with a Securom patch afaik.
Fallout 3 was slow as hell until I installed a user generated patch that removed GFWL. The mouse was barely usable in the main menu and the game itself crashed and generally ran extremely sluggish.
Dark Souls was already mentioned which was practically unplayable on PC before dsfix and mousefix.
Oh well, I still love PC gaming and most of the problems I had in the post DOS era were due to copy protection (which never kept anyone from copying the games in question) or additional software like GFWL.
