Game you wish you owned: at the moment I am good. Between my brothers and my neighbor we have a ton of material between pdf and physical. Most of the things I want I can purchase, but much of my time is hunting down ideas and writing my own stuff, so not a ton is driving my interest at the moment.
Longest game session played: one year a bunch of cousins and I played for something like 5-6 hours in camp chairs in the middle of the desert while camping.
When last I posted I mentioned how my currently developing campaign is being put togeather. Once I had the concept of 9 planets in a binary star system that are habitable. The other thing of interest was basing a campaign off a world with mysteries, with xp awarded for the standard dungeons and dragons things, but also for completing personal goals and discovering mysteries.
While I have not finished how to create random mysteries in addition to world and national mysteries, it remains a compelling ingredient to my campaign. I am compiling interesting tidbits, like this interesting flask I saw at the ren faire.
