Has anyone ever suggested something like this? Reminds me a little of Axis and Allies, how you could choose to spend money on R&D each turn.
What if each map started with B-29s, Ar234s and 262s disabled, but players were able to create, say, 1 hour-long kickstarter campaigns where all the players in a country could donate some portion (with a max limit per player) of their perk points to "develop" (read that "enable") them? And add to those options V1/V2 rocket launch sites, and a Yamato-class battleship?
If the kickstarter campaign fails to reach its goal within the time frame, you get your perks back. If it makes goal, that weapon is available for your country's players (at their normal perk cost) until the map is reset. In the case of the Yamato, it would sail with a task group from a designated port. V1 or V2 launch sites would need to be pre-built into each terrain but remain disabled until a successful kickstarter campaign. After they are enabled, a player can spend perks to launch a rocket at a target of their choice that is in range. And these launch sites could be valid, destroyable targets for opposing forces.
The clipboard could have a function to show everyone the progress of all the countries' kickstarter campaigns. It'd be like an arms race. Might add an interesting competitive dimension to the game? For balance, outnumbered sides could have smaller kickstarter thresholds to release the weapons.
I think I'd like to see additional ways to earn perks too - for example, spawning a plane in a hangar rather than the end of a runway, so you actually taxi to the takeoff point could earn you extra perk points. And maybe landing and using a rearm pad successfully. Or ending a sortie by exiting while inside a hangar. For people who have a tough time earning perks, it'd be like perk "extra credit". It would also have an added benefit of making airfields look at more realistic, what with multiple planes involved in ground operations.
