As someone with the same mindset, I recommend a few things. First, I'd say stick a server with 20 people at most. That's my comfort limit if I'm just exploring. If I'm looting I am for empty servers. Secondly, find a few people to run with. I'm not saying a clan, just a few buddies to help. I'm usually a solo guy but those long ventures are a lot more enjoyable/safer when you have someone to talk to. Lastly, GET A GUN! Even if you're on a low pop server, there's no reason not to. It's not going to get you shot more than being unarmed is. Just learn how to quickly put it away if someone asks you to. Those few seconds can be the difference between life and being a coastal cutie all over again. If you learn where to find good loot quickly, you'll care less and less about dying. I can be kitted out in under an hour so I make contact with every person I see.
