For example here is the Macintosh version of Dark Castle, which I spent some number of hours winning at the time (circa 1986, digitized sound was still a brand-new thing) https://archive.org/details/mac_DarkCastle_1_2
If you hit "Options" you'll notice the familiar WASD keyboard control layout. Well, this is the earliest game I'm aware of that used that layout...
Here's The Dungeon Revealed, an early Mac dungeon-crawler I also spent a lot of time in: https://archive.org/details/TheDungeonRevealedMacintosh
Here's Crystal Quest, the first color Mac game (although the emulation is in black&white which was also supported): https://archive.org/details/CrystalQuest_2_2_5M
Here's NetTrek, one of the first LAN multiplayer games I ever played (was fun!): https://archive.org/details/NetTrekTheRealVersionMacintosh
And then there is Bolo, the one game I wish there was a modern-day version of that is remotely similar: https://archive.org/details/BoloMacintosh (Wish this was the color version, but anyway... It was a network tank battle game where you could capture points and build autotargeting defense turrets by harvesting trees via sending out your tank pilot (who was then vulnerable and could get killed, the respawn penalty was not trivial as I recall), it was INCREDIBLY fun at the time, literally hours in the computer lab with a group of other nerds)
It's amazing that I can even give other people a hands-on look at this stuff in their own browser. It's too bad that I can't show off the early network-gaming the same way (firing up Bolo or NetTrek in different browsers on the same LAN... It's probably possible to do, right?)
