You've been granted the ability to play life like an RTS game. This grants you the strategic and tactical ability of history and fiction's greatest generals, as well as an ever-growing internal energy source that can be used to summon buildings, units, objects, and heroes at will.
At its core, the power operates on a tier system. Initially, the user can only access and summon a couple dozens of tier 1 and 2 units a day, on-par with the technology and capabilities of 21st-century Earth. However, by acquiring one or more Technology or Artifice powers, the user gains the ability to summon armies from the referenced setting or settings. From medieval knights and fantastical creatures, to futuristic mechs and advanced alien races.
The internal energy bestowed upon you serves multiple purposes. Firstly, it can be channeled into research, unlocking new technologies, units, buildings, and so on. Each technological advancement provides access to stronger and specialized units, enhancing your battlefield capabilities.
Investing energy in upgrades allows you to transform units into elite warriors with enhanced skills, abilities, and equipment, such as Astartes with 40k tech, or Mammoth tanks with Command and Conquer tech. Buildings can also be upgraded to increase resource & unit production, starting unit quality, and other capabilities.
Periodically, you receives opportunities for significant advancements. Minor upgrades can be performed weekly, advancing your current technological base by 5-10 years. This may involve temporarily boosting research speed, creating new tier 1 units, or upgrading existing units to elite status.
Monthly major upgrades leap you forward in time by 30-50 years, encompassing an entire generation of technological progress. This grants access to upgrades for specific units and unlocks higher tiers. These advancements revolutionize your arsenal, enabling you to bring forth powerful and advanced forces that no foe could hope to match.
