I played most of TG when it wasn’t much different from Bee.
Silicons: I have good understanding about silicon policy and general knowledge on how the silocons should operate. I know pretty much every module and it’s tools.
Engineering: I’ve spend lots of time doing and watching others do weird and unusual SM setups. It has been long time since I setup the singulo but I don’t think it should be that hard. I’ve never done antimatter and tesla but they both seem pretty easy (wrench some stuff into set places and activate the engine). I know properties of every gas and I have good knowledge of pipes and other stuff, but I’ve never done fusion.
Medical: I know all surgeries (they’re pretty easy if you think about them), I know the factors that make you fail them, I know self-surgeries, etc. I can revive most of the races without needing to clone someone. I can treat every injury and I know most of the chemicals. I can’t do viro.
Science: I can make maxcaps, I know the research nodes, I can make super-human nanites and utilize most of their programs. I know mechs, cyborgs, laws, making AIs etc. I know the basics about xeno (feed monky to slimes, inject cores with plasma/blood) but I never tried it myself.
Service: I don’t know all the drink/food recipes by memory, but I know where to find them. I don’t know botany (I can plant and grow food just fine but I don’t know anything about mutation and gene manipulation).
If you need anything more specific I’m more than happy to answer any questions.
