Asking this because I worry that at only 15 dollars, we will maybe get a game that's reflecting the price tag. Cheap, not very polished, corners cut, not much asset density and detail. I worry that it will not be the same as a full priced 3d platformer of the old days it's trying to bring back.

Obviously the KS funding won't be its sole source of income, they usually have other streams of funding/investors, but it usually doesn't exceed a couple million extra. That said, there is clearly a demand for this genre. I wished they'd ask for more to make it the best it can be. With a ~30 bucks a copy baseline like Bloodstained, the KS would be over double the amount pledged now. There's 50,000 people who've pledged already and considering they're the early birds and hardest of the core with more than 30 days to go, the amount of pledgers would still be more or less the same. Also, the last few days the backers per day has really gone down, which is normal, but it shows a low price tag and few pledgers hardly make a dent, it relies on mass pledges.

I'm sure they'll manage with the £15-$15, I find £20 to be the sweetspot for some indies, 25 might be pushing it though and 30 will have some people questioning in it's value and then anything upwards of 30 will probably put quite a few off.

Why? They aren't paying anything to make it...?

With a cheaper price, there's a higher chance of more people buying it too..

Yeah sweet spot is probably somewhere between 20-30$.

They just need to get Sony & Microsoft to help them, with physical disk releases and marketing.
Game can still sell bonkers (as long as they make enough noise, people need to know about it).

But think about it like this;

theres like 7 guys there only.

7 guys shareing 2,5million $ (so far) is enough to pay for some pretty decent wages.

The development is already funded. Only the final sum is relevant, not the price of the individual game. And $15 is not really less compared to what developers of full price retail games are getting after marketing, physical production, distribution, shipment and retail costs taken into account. Usually half of the final price goes to retailers alone.

Would probably better to have a third party publisher help them. I dont think Sony for example is interested in helping them release a XB1 or WiiU physical disc...

Really for what its offering it should be $30, but they've already broke even because they haven't had to fund the game themselves so I think thats reflected in the pricing

Content wise a 1-1 recreation of Banjo Kazooie wouldn't be a hugely expensive game,

30-40€

Do you honestly think if it just only reached it funding goal of 75k GBP, it'd be the same game? Indeed final sum is relevant, but with a higher individual price, the final sum would be much higher. Also all those costs you mentionned, do you think those don't apply to the creators of Yooka Laylee?  Steam takes 30% and they're making a physical pc version as well. They have to market it, produce the discs, sent out the physical rewards, shipment, distribution.  So that $15 is even less actually.
