I think you worship ideas a bit too much. For example, I don't write down nor archive ideas at all, the premise is if I manage to forget about an idea it means it was not good enough.
This might be a detrimental thing because you might get more inspiration about the idea a few weeks later that greatly enhance it.
It's also good to see the general direction your ideas go (I have a mod-able trend currently) so you know what you desire out of all of the ideas. I've written down several ideas for games where the player starts with a blank slate and the community creates what they want with the game engine. This shows that I really want to play a game that is that open and expandable. Games like Minecraft and Half Life 2 are similar to this but the entry level for modding such games is much higher, whereas my idea would have modding practically in-game and intended.
Finding the game you truly desire to play is an oft-recommended formula for a good game, so watching how your repository of ideas changes over time could be a good way to find that game.
