hardcore video game nowadays has really come to be "art" of some sort when it's done right. Facebook app and iPhone app type game will never be on the same level. however, will the hardcore game start to dwindle in number? i think so, and it has dwindled since the PS2/Xbox days. Development cost is high, talented coder is required, and long session of voice recording, QA etc are required to make a great game. Making a great "hardcore" game (if we start using that term to distinguish games that are full scale on console/pc) is like a great painting: it requires effort, time, and money; however, the reward is high, and the prestige is high.
