Valve is directly responsible for skins in Counter Strike which are gotten with 100% gambling mechanics. The fact that they can be sold for real life cash adds to this. I’m not saying its only Valve doing this, plenty of other games on Steam as well, but they certainly have a horse in the race.
Not networked and running on some legacy-as-fuck software. Saw quite a bit of this working in hospitals. You would be surprised how many medical devices are still running Windows XP.
