I know I'm not the only one looking for one: a star system which contains at least one gas giant of every Sudarsky class. It's much harder than it sounds, because you need the Stellar Forge to give you gas giant generation across the entire temperature range of a star system from super-hot to super-chilly, which you usually don't get.
I haven't found one yet, but I have found an "almost a winner". It's got a Class II, Class III, Class IV, Class V, a Water-based life and an Ammonia-based life. It's only missing a Class I to have one, and only one, of each gas giant type. So it's not a true "winner", but still good enough to get a screenshot. (System ID to be revealed at a future date).
Anybody found an actual "winner" yet, that they can share?
