I hope someday, when the Custom Arenas settle down, the Custom Arena hoster will be able to activate a previously written "Offline Mission", activating computer-generated "bot" aircraft that others in the Custom Arena could see (and shoot) like in Aces High V2.12.4. (Back in the old H2H days, this allowed large-scale, cooperative combat with and/or against bots, which the live humans could join, oppose, or ignore.)
