I can explain, we did changes in price since 10+ years, they increased. As Anarchy noticed, seems like AdvExt remains the only one public team on the market(at least for sure in L2OFF), because we built the business model which gave us resources to be active for all this years. I guess that all understand what is a real market value for senior developers?
Also @Anarchyis right, that serious customers are ready to pay for the project quality, which help them to earn a lot of money. And not 10k USD, much more. The idea that l2 is dead - is a myth, I heard it thousand times since 2008. and it's still not. Amount of players are not so big like in the 2006-2008, that's true, but the community are stable and with medium age 25-35 years, who are ready to pay for their hobby. The most important thing, why many old members from l2 admin community thinks that l2 is dead - because market changed, and they didn't got into it, right now is not enough to invest 1k EUR, to install a plug and play server and that's enough, and now is almost impossible to work under server alone, because too many things need to be managed - technical questions, game design, monetization system, advertising, community management, clan relations, media marketing, direct advertising, analytics, in case of that, in last 5 years VIP contracts with our old and successful clients gives a majority of our income, much more then 1 time sales, and we are interested not to earn some money from a random sell, but to provide a quality product and service to increase chances in success for our customers, and to build a long-term relations.
