CM: those will get the 30s freetext, but be part of the others 30 texting
Literally, you can do a list of any 30 related things and qualify for the freetext and linkage. Thirty is just a common benchmark for completeness we sort of adopted.
And don't forget, we can have more than one of the same 30. Check out the Princesses. so choose something that someone might actually use in a game, and do that.
30 Beings in the Starport Bar
30 of the Lab
30 Cab Drivers
30 in the Kmart
30 in the Airport
30 in the Slums
