I played a Not-Skaven Operator/Mechanic hacker engineer in a couple of “let’s try this out” games with some friends back in Michigan when it debuted. It’s been my experience in sci-fi games that hacking is too often either utterly boring “Roll your Computers skill. Okay, you passed.” or painfully overly complex “Okay, I access the LTG then try to hack on to the RTG, then the next LTG, scan for the GPC, USB, GPU. How much ICE is on the TLA?”
Hacking in Starfinder was actually quite a lot of fun. Without becoming just a boring yes/no skill check, a complicated mini-game like early Shadowrun, and not some thinly veiled rehash of a spell-casting system. It was also equally useful in social/investigative scenes, face-to-face firefights, and starship combat.
Plus, I was an chainsmoking, foul-mouthed anthropomorphic rat with a Scottish accent. Always fun.
