It takes a strong company to make a game look good after 3 or even 5+ years. World of Warcraft is the only game I know that's been here that long along with Runescape. You have to be in a team that is well coordinated and has employees with a good mentality on the gaming industry in the present time. But I think so far it's a big challenge because companies are competing to market some of the more popular MMO games in the Asian market. It can be difficult to find a good strategy to push your company out because there are so many other MMOs out there. Companies have to work hard to find out what players want in a game and bring it out.
