Don't see an edit option on the app, so replying.
Re-read the description and saw the topic on price. Apologies.
However, a 1 month or even a week free subscription time can be substantial, as players will be able to see if this is the game for them, and when their subscription ends, the type of players that these complex strategic games attract are generally players who would play long term, and lifttime subscriptions would definitely be something most hardcore gamers would be thinking about.

Just my two cents.
