Now that I'm somewhat more articulate, allow me to speculate on what could be a future reality of PZ. I personally love the idea of branching AI behaviour, so many events and interactions taking place independently from me as a player. Some I'll be involved in providing some truly stunning emergent gameplay, which personally speaking I think will even exceed other games I LOVE playing for this reason (prime example CKII). However, I'm also head-over-heels-in-love with the idea that these situations will occur and during a bit of scavenging or exploration, I'll stumble across the aftermath, and never be able to predict or fully anticipate what I'm walking in to. For me, that's what really makes the post-apocolypic genre really pop. I approach a house, surrounded by a white picket fence. For now, I think I've left the horde shambling around a couple of blocks behind me. In the garden lie the remains of two men. Men, not corpses. They're dressed like they mean business. Searching their bodies, I find rucksacks full of loot, and they're carrying weapons. At the doorway of the house, lies another man. He too is armed. Were this pair of men looters, killed by this lone man protecting his property? Did they all travel together, and for whatever reason this lone man was murdered at the hands of his companions? DId anyone survive this skirmish, and are they now hiding from a safe distance, watching my moves? Are they friendly? Do they want to do me harm? Am I alone? Is anywhere safe? Outstanding work fellas. As a gamer, playing a game which can encourage this sense of narrative goes far beyond anything I've seen to date, in any form of media.
