I think the fact that theyre small means a good launch is absoutely critical to the games longevity and this is not a good sign. Taking another mmog as an example, WWIIOL had huge hype before launch, lots of people bought the box. On the actual launch day it was a nightmare and only a couple of percent of players went on to pay the monthly fee. The game struggled to survive and it was only because it was very much a niche market being both an FPS MMOG and a tank/plane simulator with ultra realistic damage models that a select couple of hundred grognards kept the game ticking over until it became playable. And some would say theyre not there yet, many years later.
I cant see any reason why they cant get investment in darkfall which would let the development process continue for a couple more months, theres more than enough expectation in large sections of the gaming community - it just seems theyre very unwilling to let go of a chunk of their intellectual property in exchange. But its so clear that they are unready, and blaming 'ISP's in america having problems' and 'running out of digital downloads' cant hide the fact that they are seriously out of their depth in a relatively basic area, getting the client out there in exchange for a large wad of cash.
I hope hope hope im wrong, but the way i see this going, as has happened many times, is the hype means a massive influx on launch day, server lag and wholesale crashes to start with until some sort of stable client is established, then bugs and exploitation to the nines till a number of patches have been brought out. possibly a world reset. The forums are a screaming mass of discontent, the first reviews pan the game sideways and a large chunk of the players go back to the games they actually had fun in.
Fingers crossed, the game will survive for a while on all the digital download sales, and left with only the dedicated might actually be quite an interesting proposition at this point. Youre looking at april anyway.
I agree entirely with what you say and feel pretty similar about DF. The thing that DF has to its advantage is the fact that it has a tried and tested ruleset in games like UO, Asheron's Call, Shoadowbane, SWG and DAoC and the fact that there's nothing like it on the market at the moment.
People that played those sandbox games are craving something similar and are willing to support the game through thick and thin, they don't care about how polished it might be or how bad it might be at launch as it's worth it in their eyes.
