Likewise, there is a subscription model that allows you to maintain access to the title and is divided into two types: Centurion (€12.22 per month or €134 per year) and Imperator (€24.44 per month or €268 per year). The Imperator offers, unlike the Centurion, exclusive events and an allocation of in-game money per month to rent ships and weapons.

Some pretty sloppy work here. The subscription options have nothing to do with playing the game; it's a buy once product with no subscription system at all. The Centurion and Imperator subscriptions are better thought of as a kind of "backstage pass", they mostly just give you patreon style content and extra in game flair items. Are they worth the money? Unless you're a die hard fan, absolutely not. But it's not like you have to pay up "maintain access" as the article puts it.
