I played this game, got a really nice tall house with 5 steel doors just to find those 5 steel doors blown up by C4 the day after. I promise you that if you play on a server with raiding enabled you can never make your house secure enough. And don't even try to go on a server with 80 people you will in 99% of all cases have your house ruined before you wake up next morning, and playing on a "no raid" server is not fun :/
All that being said the game is just awesome, reminds me of dayZ only more fun.
