I don't really 'get' DayZ, but I also know that it was a pay-once game, not free to play. Once you've paid the money you might as well get your fun out of it. But if you're constantly losing items and getting frustrated by bugs what's the incentive to keep playing and possibly giving Niantic money?

Because we're believers! And there's no subscription cost and we've already paid, and all our friends play it too, I guess...
