I can't believe you still don't get this game!
Sadly, there's a lot of people that don't.
But back on topic, food relly isn't hard to come across nowadays, and as long as you don't sleep a character to death, it's really, REALLY easy to survive. It's hard to build cars, but survival isn't a challenging issue 90% of the english islands nowadays. Unless, maybe, you're playing a complete loner that doesn't cooperate with society at all.
If you're running out of food, get out of the mountains
Point is, I love that there's a new disease, or sickness, and that some of the more interesting characters/players can rp out a challenge and work towards something more than simply trying to get steel weapons and a vehicle. Whoever finds the cure has a potential to make good profit from it, until CRBs ruin the whole thing.
....Am I the only one that enjoys the chance of RPing a challenging lifestyle, and even RPing death when it comes to it?
