+ Core gameplay ist fun - Can't quit a battle without destroying my own ships??? (Seriously, even back in 2016 people had real lives and not always time to complete a mission...) - Connected to last point: only one saveslot for each campaign and no way to save manually -really?! - Some missions are just annoying, for example: campaign mission with two subs as enemies. Damaged both but they simply left the battle - which doesn't count as success therefore I couldn't proceed with the next mission. Some might consider this "fun", I don't.
