I know I can't realistically take it any further because it would be time consuming to get any concrete progress done with "indie"/home brew methods.
Yes, it would be time consuming, but you mentioned that you've been thinking about and developing your ideas since around 2001 -- that's 12 years ago! -- is it not worth putting in the time to take your ideas further and hopefully create a playable game? With a bit of dedication and effort it could take significantly less time than you have already spent to flesh out your ideas into a working demo or even a complete game!
It's likely that the best direction you could take to proceed would be to either:
- Develop your ideas as a mod for an existing title rather than as a stand-alone game.
- Distil your ideas down to the basic concepts so that you are able to express them through significantly smaller (perhaps even "mini") games that are much more approachable for a lone developer or very small team.
A third option -- especially given you mentioned you were happy simply to play your ideas and aren't bothered if others develop them -- might be to simply put the ideas out there for free and see if anyone picks them up. An example of this is Three Hundred Mechanics, which is a large list of one person's ideas (some basic concepts, others almost fully fleshed out game concepts) provided for free for anyone to examine, use as-is or take inspiration from, and many of which have since been used in different games; there are some example links on the "about" page.
Realistically for your ideas to become reality, you'll either have to just put them out there and hope, or you'll have to invest a lot of time, effort, and quite probably at least some money in order to make it happen. Personally I'd look into developing the skills for mod development, and then pay others to produce assets such as art and audio. You can then either develop the entire game yourself, or at the least can produce a working demo so that you would actually have a chance at the opportunity to pitch the idea. The barriers for entry to creating games are getting lower and lower, and with products like Construct 2 and Game Maker and the ready availability of top-quality engines such as Unity3d and UDK it's less daunting than it's ever been to do your own development -- you'll always have to put in the time and the effort, but all of these great tools are there waiting for you to pick up and use them.
Hope that's helpful!
