Accretion - Design by Landfill: A Long Term Strategy? (2016x45)

:

Accretion happens when, instead of fixing broken mechanics, developers just build new ones and let the old ones become obsolete. It allows longterm projects like MMOs and yearly sequels to keep going as the new teams pick up where the old ones left off, but it can also bog the game down and make it completely inaccessible to new players.
