Would be pretty cool if we could spectate live games. For example right from the main menu we go to "Spectate" (or "Live" or ... whatever) and get the list of live games which we can observe. To toggle our own current local game for spectating we press "Esc" -> "Allow spectating" (or "Disable spectating" if it's opened to close it). If we would spectate games we would see everything just like the original player except of mouse cursor I think. Of course all of this would be full of spoilers. But if you already know all stuff or just don't care why not? It will be "ToME TV" lol

Sometime I search YT for games, but there are not so many of them and often they're out of date. Observing other's games in itself will populate game experience.
P.S. Don't know if such thing can be even possible from the technical side.
