As well as the first SimCity and a few other series that started in the Apple ecosystem.
One of the bigger ironies is how Doom was developed on NeXTSTEP then went on to make the IBM PC cool among gamers. Also the first web server if I'm not mistaken.
Thankfully, unlike the Amiga etc. the Mac didn't completely die and has been having a great resurgence in the past half-decade. Looking forward to this Monday and hoping for Apple to focus on making this platform even better.
The Amiga will never die [1] [2] [3] [4] [5] [6] ;) (become irrelevant to the vast majority, sure).
That last link is for a new FPGA based M68k clone that adds additional instructions, pipelining and other fun stuff as an accelerator for classic Amiga's (it sprung out of the ashes of the now defunct "Natami" project to create a new M68k compatible Amiga-compatible machine).
As someone who has contributed code to AROS (AmigaOS compatible portable OS), I can confirm we're crazy. For my part I'm not hardcore enough to have any Amigas any more, though I want to (I have a Minimig, though - an FPGA re-implementation).
It was, but not until over two years later as a Mac port of a Windows port of an Xbox title. That was done by MacSoft, Bungie (presumably) having been tasked with sequels on Xbox as soon as resources freed up from the original.
After the Bungie sale, Xbox was the primary platform they designed for. Before that it had been planned as a Mac/PC title.
Somewhere I have DATs with like 1GB of custom Marathon levels and texture designs. Including a complete model of our Junior High School a friend of mine made. I'm not sure how I missed the announcement they open-sourced them.
And the Mac version was a very different game from what Halo on the Xbox turned into. You can find old trailers. Among other things I think it was 3rd person with a heavier emphasis on vehicles.
The Mac version was the same as all the others at release, Microsoft had Bungie dumb it down for the Xbox. The trailers you are watching are for what HALO was suppose to be, not what it ended up being.
Everything (modern, not DOS) debuted on the Mac first in the mid-end 80's. Windows was not a viable first platform until 3.0. I worked on three apps all of which debuted on Mac and two were eventually ported to Windows in the 90's. By the time Office took over the Mac become the second platform or not at all.
I think the Macintosh doesn't get enough credit for what it inspired at the time.
