Well you really went through for the 1975 founded document? Did you know that microsoft paying about mill, to hold back source codes, as they must have released in order to be legal. We are talking about windows in 199X , It would be absurd if a company exist who developed dos games in 198X to 199X and would report violation, the first question would where is the published source code my friend... Well grey zone, but pretty sure what you can obtain from abandonware or GOG are completely ok, rest just ignore them or buy (if you find)... 30 years softwares , my 10 years old optical disks not readable anymore not even my orig games, what about magnetic storages from 198X-199X pretty sure they also KO..

Ur list:
I have a monsterous collection of good games...
My all time favs...though...I just can't get enough of...
masters of orion 2 ...great fun...
Dungeon Keeper 2 ..one of the best games ever.
Heroes of Might and Magic 3...just charming...
until this all fine But rest not
I miss names from other bullfrog or simtex games (both company RIP) like master of magic (best forewer), magic carpet, popolus 3 the begining (last game of bullfrog)

But moO2 high upward rating replayability and difficulcy and complexity of the game make it absolutely on of the best all time.
What about early westwood and blizzard games? RTS warcraft series and C&C+RA and dune 2 RTS ? and if we moving toward windows 1998 and upward with homam3 where is startcraft and warcraft 3 , I remember they were the most serious names even ms published the age of empires Starcraft is the main name on RTS hall of fame, just preordered war 3 reforged as well... just with that 2 sequel blizzard one of my favourite game publisher , even they now digging the earth under themselves with new decision and Activision merge...
