Guys, like I said, siiiimple and no one has touched on the full immersion thing
Full immersion is purely a lifestyle which means you pay out the ass to never actually be on the scene of the run.
This lifestyle is for those who wish to live in a virtual environment all their waking lives. These people have literally left the meat behind and exist only as their digital personae. They trust the care of their bodies to medical professionals, who keep them on elective life support. Hydration, oxygenation, nutrition, excretion, muscle toning, and every other aspect of long-term care are handled by drones or trained personnel, all while the client interacts with the rest of the world via VR or by jumping into drones. A character with this lifestyle also enjoys the benefits of the Hospitalized lifestyle, but must still cover extra costs for treatment or surgery.
Cost: 30,000¥ a month
So, if you're not netting 30k a month, you'll soon be out of your VR only life and stuck running in the meat. Also, weren't you the one to complain about your
GM disliking the Matrix? This seems a very bad choice on your part if this is the case. Sure, he's gonna try learning the rules, but still.
Long and short, the only thing people should consider leaving out of their advice to you )as relates to full-immersion) is bits on surviving in the meat. Everything else they've said is valid. You still need a commlink, with a pile of good programs. And some serious bio/nano/cyber ware wouldn't hurt you, either.
On the other hand, full-immersion means that any time your team goes high-sec, they'll have to string out toasters to keep you involved in the run, since a good high-sec area will be isolated from the wider Matrix. This leaves you tenuously (at best) connected to the game. Frankly, full immersion is a bad idea for a new player, with a new GM (who is uncomfortable with the Matrix rules), in many running situations.
