Doesn't surprise me. Their credits state that they had a pretty large team to make the game(about 20 people). I'm sure that some of them weren't full time but if you keep that many people employed for a year on a typical salary ($40,000+) and you end up with a very large number. Figure in that a large chunk of their sales came about when they sold if for $2 on Steam and it starts to make sense. Now factor in that they have continued to support the game for the last four years.

Hi Adam, understand your skepticism based on things I read as well, but we're being completely up-front with you. First of all, Resurgence cost about $200,000 to develop and You Monster cost about $300,000 to develop, so DG:Containment at $250,000 is a pretty accurate estimation of what it will cost. AMD and Razer, remember aren't contributing any money, they're promoting the kickstarter, providing pledge rewards, and working with us on the new engine to make sure we support some of their existing and upcoming technologies – they’re providing technical support on technology integration, but they aren’t paying for any development of the game. We're being extremely efficient this time around not only building Containment in the first $250,000 but also making progress on the DG2 engine during that time.
As for your second question about "could we honestly not get funding" it pains me to hear that, not because I don't agree with you, that it should be "obvious" that someone would pick it up, but honestly over 20 publishers have expressed interest over the last 3 years and we did literally a hundred or more presentations and meetings, and term sheets, and everything, and in the end, not one publisher went forward. They were always excited at first, they were always eager and liked the idea of working with us, and they always decided not to move forward when they did their market analysis saying "it wouldn't be profitable enough, for them to choose to work on it" - they needed higher profits than they could forecast based on what we would earn for the game for them to decide to do it.
I'm sorry you think we have another choice - we don't. We really want to make DG2, but I'm pretty sure we have exhausted every other possibility over the last 3 years in trying to get this game made.
