My suggestion is to add accretion disks to some black holes (leave some black holes without). The elite already have a ring generation model. In this game there are rings of tens of millions of kilometers. And there are also huge luminous stars. It turns out that we already have huge wide rings and huge luminous objects. So what prevents black holes from adding rings, just replacing their texture with a glowing one? Slightly change the mechanics of light distortion by a black hole, and also prohibit players from flying into such rings due to too high a temperature. And here it is, done! Such accretion disks will look very interesting and bewitching.
