Nethack is one of my less favorite roguelike , i prefered a lot more Angband and ADoM at the time.
Thinking about some non-PC games i enjoyed in their time, choosing titles that were also not mentionned in this thread yet .
On Amstrad CPC
The Way of the Exploding Fist , similarly to International Karate that was produced later the game was very inspired by the coin op "Karate Champ", i liked a lot the simulation aspect, this sport duel aspect was very original in a time in which beat em up was the norm.
Silent Service , how much time spent with this subsim, even with how limited it was at the time in comparison to modern sub games i liked the tension and feeling when destroyers were circling around your sub.
Redhawk , a very original adventure game following the tracks of a journalist guy that can transform into a superhero , the originality was that it was presented in 3 panels comics sequences, and you were free to explore the city , take taxi, fly, go into trains etc... and surrounding and do superhero things (ah the "punch mugger"
) or journalist "take photo" , i had a lot of fun with this one. There was a background plot you could completely ignore (bad choice as the city exploded then in the end).
On Atari ST
Hunter , a breakgrounding game for its time an "open world" large environment to explore, vehicles and enemies, i liked surfing around the sharks and enemy boats.
as someone mentionned
Dungeon Master already, i'll point then to
Chaos Strike Back its sequel, i remember drawing maps for this one, some floors were tricky as at the time walls graphics all looked mostly the same when a tile teleported you it was hard to figure out where you landed
Sherman M4 , a great great ww2 tank sim, several theaters, artillery shelling around, you could give orders to other tanks in your platoon, bringing some tactical aspect in real time, loved that.
Super Nintendo
Street Fighters 2: World Warrior , on my late school years we used to play this one a lot between courses in a bar that was next to the buildings. When it went on a release on a home console, i couldn't resist , a friend was even more crazy and couldn't wait for the release in our country and imported it from Japan (and even had his console modified to be able to run japanese version of the cartridge)
Super Mario Kart , while "only" just good in solo the real strength of this one was that it was tons of fun when playing with a friend in split screen, such a jewel of a game it was like that.
On Nintendo64
nWo/WCW World Tour , i played that at a friend and was so amazed by how good it was that it became the reason i bought a 2nd hand nintendo 64, it was the 1st game of a very acclaimed and respected wrestling serie, just brillant fun.
Goldeneye , had to get this one after reading all the praises in game magazines at the time, never regretted the purchase, it was an incredible game with tons of replayability and good level design. Funny that i watched the movie only after having completed the game (some insane difficulty to unlock the last levels sometime failing at a second or two)
I'm a lot into emulation to fillfull my own nostalgia, but it's also sad how some of the games that i found brillant in my youth have aged so badly, fortunately there are some that stood the unforgiving test of time
