A loving friend who just bought ArmA 2 for DayZ is a better Rper than you.
I'd just buy that for the entertainment at first. If I get interested in the Rp, I might try it out, but I would believe that DayZ wouldn't be bought solely for its RP capabilities.
Also, Svernloch rescued 100 refugees from Syriiak so far. Since Watcher started a new country of the Syriiaki people, he may chose to absorb them into his society if they are willing to join. However, most of them have severe radiation sickness, and some have quite gruesome mutations. If you're not going to take them back, Svernloch will be glad to at least build a monument in respect to the millions of victims of a nuclear strike by their own mother country.
