I have only found this game 2 years ago and I played it for weeks.Master of Magic has aged extremely well. I even manage to still find the graphics "cute", despite their horrid 320x200 resolution.
I encourage everyone to stop being nostalgic and just play your old favourites again. They are still good games and you can still enjoy them. 90% of my playtime goes to 10 to 25 year old games. There are only few games I could not get into again, most of the time because of annoying interfaces.
So to be on topic, games I am very nostalgic for, but could not play again:
-Amberstar and Ambermoon (to my shame, I will play them again eventually)
-Seven Gates of Jambala (jump'n runs I could only enjoy at age 10)
-Secret of Monkey Island (adventure games became to simplistic after puberty)
-Dune 2 (interface is a nightmare)
-History Line/Battle Isle (interface again..)
-Rise of Nations (not that old, but recently tried it again and it just seemed tedious and annoying)
-Anarchy Online (MMOs destroy your creativity, wont ever again play any)
-Goal! (dino dinis football masterpiece, cant play properly without joystick)
Some nostalgic games which surprised me in that they were even better today, because I fully understood them:
-Xcom:UFO
-Keef the Theef (fun unique RPG)
-Speedball 2 (it is amazing how much fun this one still is)
-Pizza Connection (love it)
-Capitalism 1&2 (learned to fully appreciate them only when I was older)
-1869 (very surprising that this simple trading game is still fun)
There are tons more, for about 4 years now I pretty much play old games all the time, and if not, I am playing remakes, like Civ4, Fantasy Wars or Kings Bounty. 99% of new games are crap not worth bothering with, in my opinion. The only new games in the past 5 years that were not remakes or new editions and that I somewhat enjoyed were Stalker and Just Cause.
