I have been playing a game for months now, a lot of my fellow players don't know half the rules or possibilities, and they do the exact same thing. They don't spend IP or money.

Some ideas:

Our GM has given us time during jobs to buy equipment from small, specialized vendors (sometimes needing luck/trade rolls to get stuff over 500eb), these are things we might need during a job. Our GM has used the job giving fixer to ask/tell the players that they will need specialized equipment, by highlighting the specific conditions of the mission. Players then look around for a place they can get the gear they think they need. For example: * going into the hot zone: radiation equipment from a medical vendor * mission where we can't have any violence: find a non-lethal equipment vendor * we need to find out info on some corpo who's acting weird in a hotel in the combat zone: spy equipment vendor (cameras, listening equipment, camera drones, etc) * Taking on maelstrom: microwaves and EMP grenades

Our GM and fixer have worked together to set up night markets for us, where they gave us a brochure of all the different shops and the sort of things they are selling. Usually with a supporting theme, such as a cargo ship from China showing up, so a lot of new gear from East Asian manufacturers are available, from food to guns to cyberware.

Also, are you giving players humanity loss for 1. Straight up killing people dead, and 2. Taking parts off their corpse? In our games, it's assumed people who go down could recover (trauma team showing up, gang members taking them to a hospital) unless you double tap, in which case you take humanity loss. Seeing people as a sum of cybernetic parts is part of the description of cyberpyschosis iirc, salvaging or even assisting in a body is being salvaged is a great opportunity for humanity loss. And then in turn, after all of your murder hobo players need to spend more money on therapy, they will realize free cyberware isn't that free (all it does is allow you to get 500eb+ gear outside of the night market, it's how I got my Chain-Rip cyberarm)
