He is joking...
To make a game like runescape will take you more hours than you have in your life (especially seeing as it looks like you need to learn to program first...), and nobody's going to help you unless you can show that you are a very experienced programmer (which I doubt) and have already made a lot of progress.
Almost every day there is a new post like this, where someone completely new to game making comes along and fancies them self as the creator of the next MMORPG.
Not one of them has ever made any real progress on their game, and most of them leave as soon as they discover that you actually need to put work in to make a game...
If you have no experience programming, but you want to learn, you will probably be better off with DBPro, which uses the simpler BASIC syntax instead of C++. If you aren't going to put the effort in to learn to program, get FPSC instead.
Finally, don't even bother trying to make an MMORPG, because it is a fact that you will fail. No MMORPG has ever been completed using DBPro or GDK, and the only projects which have ever come close are by very experienced programmers, with teams of people helping.
