Foreword: I am posting this on answers.onstartups and gamedev.stackexchange because the expertise from each area will likely contribute useful information. Also, I saw similar questions to this, but I still want advice. So I'll change this question to: where should I go from here? What's the next step?
So this morning I'm taking a shower, when suddenly I have an epiphany! The greatest idea I ever had, and it's about a dynamic 3D persistent-world MMORPG that breaks from the classic MMO in all senses (for business reasons I will not share any details). So I ran out of the shower, grabbed the graph paper in my room, and started jotting everything down.
Then I got stuck on something. I realized I REALLY want to make this happen, but don't know where to start. I'm going to college as a freshman in the fall, and I think that by the time I get out, it will be too late. Someone else will already have done it or be making it (long development process). I thought, do I go to a big game company, take out a big loan, go to California and get workers?
So this brings us back, what does it REALLY take to make a Massively Multiplayer Online Roleplaying Game? (considering, 3D, dynamic world, servers, sites, marketing, and everything else I'm missing). What's the next step?
