Everspace 1 is still my top favorite space fighter game because of the balance in playstyles.
If I have to choose though, I loved the hacking device, turret, and drone combo. Little captures the feeling of instantly forming a small fighter squadron to even the odds in a tough Okkar Frigate battle.
I look forward to the return of the these devices in Everspace 2, especially since I'll be able to mod them to maximize synergy with my playstyle.
