What kept Wesnoth alive for twenty years is the same thing that kept BBS door games alive in the 80s: the content was community-created. Trade Wars 2002 was different on every board because the sysop configured it differently and the players made it their own. Wesnoth's WML scripting language lets anyone build campaigns, factions, entire rulesets. Most open-source games die because the core team burns out and nobody picks it up. Wesnoth survived because thousands of people have a stake in their own content inside it. The game is a platform, not a product.
