And most startlingly: no git
Edit: y’all’re right, version control is for wimps. What’s life without some adrenaline?
Who needs git when you have a B: drive and a Save As command for tycoon43.asm
Version control? You mean this?
./src ./src_1998_11_05_added_people_swimming ./src_1998_11_06_added_death_mechanics ./src_1998_11_06_0_removed_swimming_lol
Did the developer use any version control though? SCCS has been around since the early 70s, RCS and CVS since the 80s. The tools definitely existed.
Also, it was a single dev, which makes SCM significantly simpler!
In my experience (some games in z80 and 68000 in the early 90s), version control wasn’t considered until mid-90s sometime, and at first wasn’t trusted. There were network backups, but I don’t know if they had revisions.
Merging seemed like it couldn’t possibly work well, so we would try to have separate ownership of different files. Although there would be only a handful of programmers on a team, so that was easy.
Prior to that, backup and versioning was manually handing a floppy or two to someone each week.
