Quote: "like runescape, but no skills for right now"
Ah, another one, many people ask these sorts of questions. If you have no skill, you're not going to be able to build something like this right away. The usual spiel is that games like runescape take hundreds of programmers, years to build. Personally I think that's crap, but hundreds of programmers will possibly take 1 year to complete it.
Now, how many people are going to help you build the game you are proposing to make? Am I correct in thinking it's just you? So where a huge teams would break down about 20 different tasks each to the team of x-hundred. You're going to be doing them all.
Not exactly what you want to hear, but start lower. To have your starting point as "the game that destroys world of warcraft"... You'll be there for perhaps 200 - 500 years if my calculations are correct. You'll probably not finish and never get that sense of achievement.
Try and get something small done first that you can just show as a game, maybe not boring pong, but something else like: 3D Connect 4.
When you've shown you can make simple games, try something a bit harder, 3D maze game perhaps. then, after that, when you've encountered quite a few of the problems in programming, and solved them, then go for your dream project. It's ultimately possible in Dark Basic, but only when you've got over the "No skills" problem... and that comes with time and practice.
