When does the game get fun?

I've spent around an hour walking around looking for things or people but I cannot find anything.

No guns, cars, food, weapons, etc. Is my game bugged or is there just nothing?

The one time I did come across a player (two) I was shot and killed immediately, is there anyway to not die unfairly like that? And no, I did not trust them. I was shot in the head as soon as I got a single glance at them.

I guess what I'm asking is, why do people enjoy the game? Should I keep playing until it gets good? Or is this the entire game. Walk around, look for nonexistent loot, get shot in the head and die, repeat.
