My biggest problem with auto-battlers is that you have to watch them fight. My computer should be able to do the calculation nearly instantly

buying DLC to build their armies quicker or make them look prettier

Wondering why they used DLC here instead of micro transactions

Controlling territory brings in silver, which is consumed by your attacks. Silver is continually replenished in real-time.

An energy system

There’s also gold, which can be used to purchase more units for your armies. Gold can be earned through logging in regularly. Some of the Kickstarter tiers comes with a lifetime subscription to Battledroid, which means, we’ll give you a gold bonus every day.

Concerning

If your looking for a f2p game similar to this just play Beyond All Reason.

Free and open source. No energy system or microtransactions.

Not asynchronous though.
