Quoted from fattrain:Stern SHOULD want to please there customers by "completing" their games and then they can "sell out" even more machines because people / customers would have faith in their products being the best they can be with finished and complete software
Yes, they should. But what is driving them to do so now - nothing. Because, as Stern is quick to point out, they are the only ones in the biz (for now), there is no one who is going to do it better and no one for them to lose money to if they don't change.
Fast forward a few years after a couple new guys release a couple newer, and hopefully bar-raising products they may be compelled to actually change due to competition.
