Another tidbit about game design: it's a speculative business. Aka, you pay first in order to make whatever game you're making, then you make some income.
Yeah, I knew that, but I just did a bit more research (and it's hard to find) on the sales figures, and Defense Grid didn't do the sales volume I'd understood it to have done.
How much did they then spent on free content patches and support in order to keep sales going for a longer period than their original flurry on initial release?
That I can answer... All the extra map packs and what not are purchased, not free to download. At least not on XBox live.
Arcen has always had the good fortune that AI War cost me almost nothing but a massive amount of my own time in order to initially create, and so the profits from that have enabled further projects like Tidalis and AVWW. However, a lot got reinvested back into AI War as well, post-release, but the expansions and so forth balanced that out and made it so that it was still very much a net gain for us the whole way through with AI War.
But you can't just look at the surface finances of a game company and know these things.
True, I personally usually prefer to pour through a prospectus for things like that, but it would appear Hidden Path is privately held and thus not required to publically release them. Defense Grid, however, is their only primary game (well, that they themselves are advertising), otherwise they appear to be doing sub-contracting to Valve for some of their work for things like CounterStrike. There's hints that they've done other sub-contract work in other components of Valve games but it's hard to nail down.
The only guess I have is the "You Monster" add on (which I need to go buy, download, and play, I had no idea they'd even MADE the thing) didn't sell as well as expected (and it's a biggie) because, well... by the time they released that one we'd all moved on and stopped watching the news. They've still got a hardened core of players, but the majority of us (most likely) didn't even see it.
So, yeah, you're right Chris, I probably jumped the gun a bit on that one. I'd heard reports that DG was 'selling amazingly well' and apparently that marketing machine didn't match up to actual numbers.
