A turn-based tactics campaign where your army budget isn't just a limit, it's a bank account that pays interest, so every coin you don't spend grows.
Each mission you buy and deploy a force from a points budget, then fight it out on the tactical map. The twist is economic: unspent budget accrues interest between missions, so under-committing to one battle can fund an overwhelming army in the next. Win the campaign by judging exactly how much firepower each fight truly needs.
Buying a force from a points budget and fighting it out on a tactical map is the shape of a turn-based strategy campaign, with the army-list phase that miniature wargames have always had.
The original rule is financial: unspent budget accrues interest between missions.
That makes restraint a weapon. Compounding rewards deferral, so under-committing to a battle you can barely win funds one you could not otherwise fight at all — and the campaign becomes a series of judgements about how little force each fight truly needs.
Brinkmanship is an original free browser strategy game that wraps turn-based points-buy tactics around a compounding-interest economy, turning your budget into the campaign's central decision.
