I awoke this morning, convinced I'd just forgotten a way to have players invest...in other players (well, not exactly, but players investing in a portfolio account managed by another player, fractionally sharing their profits) in an #18xx game, and for it to be interesting and fraught...but I'd forgotten.
It has been a while since I've been this excited to go to sleep...to sleep, perchance to dream.
