Wait, you want to interrupt people while they're doing what they want in order to barrage them with questions.Well, I wrote. That the polling system would be nice to integrate into the game itself. So that people playing can evaluate each item, etc. etc.
What do you think of people who canvass parking lots for polls or petitions while you're trying to go somewhere? Do you like reading the EULA in games? What if you HAD to? and then answer the questions it was asking before you play?
Oh...it's not before you play? It's an optional screen/menu that people can go to, but they don't need to, they could just choose to ignore it and play the game? Then you're right back to the problem with optional polls. They only appeal to the dissatisfied who are looking for an outlet to change things. If I loved everything about the game, why would I give up time that I was looking to spend playing it to answer questions?
Also the simplicity of a question does not preclude or determine the leading nature or bias of the question.
The question you asked...Do you think that zombies are very few? (this is a yes or no question, by the way)
What do you mean? Do you mean zombies overall in the game? Zombies in POIs (which, In a17 would sometimes have like 16 zombies packed into a 1 family home)? Zombies in the wilderness? Are you asking about the horde sizes? The wandering horde sizes? Are you asking about specific biomes? Are we ignoring or counting the wasteland? What constitutes "very few?" Early game? late game? mid game? Are you asking from a gameplay standpoint? a lore standpoint? a graphics standpoint? a performance standpoint?
Your simple question is packed with dozens of places for people to assume what you mean and answer WILDLY differing questions from what you just asked.
