I guess nearly everyone has at one point found a interesting and slightly obscure RPG he wanted to try but never got the chance because lack if players or other circumstances.
So, whats you list?
Mine:
1. Council of Wyrms
Looked interesting, playing D&D from the other perspective. But I only found it after 3E was out for quite a while and no one wanted to go back to 2E
2. Fireborn
A short lived setting from FFG. Too unknown and small so that the other people in my group took any interest in it
3. Shadowrun
Not really unkown, but my group was too much in "D&D" mode so that DMing for this game was rather impossible. Trying to set up adventures for SR the same way as you do for D&D will result in failure and no one wanted to take the extra effort to read through the background stuff etc. And I didn't want to DM but to play. (Small example, when the DM wanted to capture a PC for story reasons he did not use gas or poison but went, true to D&D style" the subdual damage way by emptying a full clip of stun rounds into him while he slept..."
4. Ars Magica
Here the problem was simply the lack of DM. Everyone wanted to play and when no DM was found the idea was dropped.
