Just a thought on price...
everyone wants a relatively cheap priced game, but to be honest it usually means the devs work harder for less money if the customer gets a cheap price right off the bat. $19.99 seems a round ball park figure for a lot of indie games, i have even seen a recent rise in that going to $24.99 and even $29.99 and $39.99 (I think Prison Architect is $30.)
Anyway, the point i am trying to get to is if you price it moderately, so you are not working for peanuts, say sell at $24.99 or even $19.99, then if things do not take off very quickly, you could have a fire sale and reduce the price to say $14.99 or $9.99. But don't start your prices at those low points, because you could be under-pricing yourselves when you don't need to. You have worked easily twice as long on preparing this game as Bionic Dues, so a $19.99 price doesn't seem unreasonable to me.
Of course this is just an opinion and you should really do what you feel is best. Just don't sell yourself short. Giving away Valley 2 maybe hurt by losing possible revenue. Where if you had given it away just to those who had already purchased it, you may have had more sales. But to be honest, I am just guessing there. I am not a marketeer or a business consultant, so my opinions may not be as good as i am hoping they are. I just thought if you had a middle of the road price, then it wouldn't be too high to start, but if necessary you could lower it a bit if you needed and not start at the bottom of the barrel.
Sorry, i'm repeating myself. anyway, good luck, looking forward to the game, i'm hoping it does wonderfully!!
