It looks like a cool idea.
Definitely won't be putting up money upfront while it's in development though.
They should go to a bank or micro-loan site and get a loan or an investor.
When dev's do this and ask for money for an unfinished product. It tells me that they have no faith they will be able to make a positive return on their product once it releases, So they feel the need to first sell it to the customer to meet their budget so they can continue development risk-free. So even if they make a completely horrible product, they already paid for expenditures up front with customers dollars. So it's not a complete financial loss.
Sorry, I really don't mean to be rude, this is just my opinion on paying for something in development.
It really does look like a pretty cool concept and I would consider buying the finished product after I was able to see the finished product in action.
I would suggest making it into an online card game in browser or HTML.
They would save themselves an arm and a leg on publishing/printing fees, then be able to reduce the price of the product without taking a financial hit, and reaching a much much wider audience at the same time while giving players a much easier time to find someone to play with (some of us don't have friends
). Of course you would be needing a pretty decent programmer to go the online route instead of publishing/printing fees so it might be of similar cost in the end, in that respect. just my 2 cents.
Thanks for sharing!
