Let me get this straight. You think that by answering yes for more stretch goals for the game, that you have to put in more money? Or the only people who can contribute in a monetary sense are the only ones who should be voting Yes? That's really gone over my head.
Almost. Far be it for me to speak for others, but when Obsidian starts a poll asking whether or not we would like more stretchgoals, I get the impression that they're asking "Would you like to put money towards more stretchgoals if we make them available?" They want to know what the public demand for them are, and whether it's worth their time to consider further goals. So I imagine that they're not just asking "Do you want to see more stretchgoals?" but "Would you be willing to pay towards more stretchgoals?"
If Obsidian wants an impression of how many people are willing to pay more for stretchgoals, then I shouldn't answer positively to the poll. On the other hand, I don't want to answer negatively to the poll either. I'm not against there being more stretchgoals available, and hence likely a release date for PoE being pushed back. It doesn't sound altruistic, but if others want to make my game better on their own behalves, I'm all for it. I myself just can't justify putting forward (much) more money, stretchgoals or no.
I just don't want to give Obsidian the impression that there is more demand (money-throwing demand) for strechgoals than there is.
It feels like you're reading between the lines when it's not required. The question is quite simple and I don't see it as a conditional question. Also, voting yes doesn't mean you have to put money in. There's no lying there. If anything, it may encourage people who have been holding off and not backed the game to put money in now. Just like the original Kickstarter. You're voting could actually sway other people who haven't backed the game. So in a way, your vote has helped to fund the game even more without you putting money in yourself.
When Obsidian put out more stretch goals in the original Kickstarter, it encouraged people to put money in. eg. Linux and Mac? You now have Linux and Mac users donating. There may have been other stretch goals which tipped the balance of someone thinking of backing the game to actually backing the game. When Obsidian released these stretch goals, the original backers didn't have to put more money in. There was no obligation.
If you've got people wanting more stretch goals and holding off voting because they see the poll as some conditional question when it's not, then that sends a terrible message to Obsidian imo. If Obsidian wants to get an impression of how many people are willing to pay more for stretch goals, then they would have polled differently. Personally, I think Obsidian should just put the stretch goals up on the Backer Portal and release an update about it. It may sway some people in putting in money that at the moment probably wouldn't including new people who haven't backed the game. At the moment, there's uncertainty which doesn't send a good message considering nearly two months has passed when the poll went up.
