Four calls for help at once, I know they are all systems being attacked because I reloaded my save.
If I respond to one call all the other systems like me less because I didn't help, most of their calls are species I am allied with attacking species I am allied with! How am I supposed to manage peace with odds like this?
The player is just one ship in a vast galaxy, we cannot be everywhere at once. There needs to be more support for multitasking, if it is like this with just a hand full of surrounding planets how are we supposed to manage an entire galactic empire?
In this case obviously you need to limit the number of simultaneous events to something the player can deal with, extend the response time to calls and events so we can get around to them. There also needs to be some sort of technology you can purchase to automatically pick up spice from a planet and deliver it to the player, with everything else going on; darting between planets to constantly pick up spice is a time best spent elsewhere.
There also needs to be an option to convince waring groups to make peace, I can avoid war myself but I cannot stop indirectly entering war from protecting allies from my own allies.
