If you make a game for a given platform, it makes sense to target the most common configuration, which in this case was 512k (not 512M btw). Even though RAM expansions eventually became popular, I guess publishers would be hesitant to put a "requires 1M+" sticker on their boxes. But man, 512k seemed like a blessing in those early days, too...

Some games simply used extra ram to hold the contents of, say, disk 2. Reducing disk loading (and swapping!) was a big deal.

If I remember correctly, Dungeon Master was the first game to require 1MB.
