The difference in technology between the Starfinder and Pathfinder settings creates great opportunities for roleplaying and environmental storytelling. Describing technology without using modern terminology can help facilitate the alien nature of a new world, and many GMs might find it helpful to write out these descriptions in advance to keep the game's pace snappy, even if they improvise when the time comes to explain. While this storytelling technique can be fun for a couple sessions, most technology is engineered to be picked up relatively quickly by end-level consumers, and it shouldn't take long for an anachronistic character to pick up on the cues more tech-savvy characters take for granted. While roleplaying a character who rejects technology can make for some fun story beats, in long-running Starfinder campaigns, this type of character is best avoided or subverted for the sake of giving all PCs access to the advanced tech equipment that creatures and hazards assume everyone has access to and uses.
