Agree. For a session, ok, a bit of a change of pace. But 3 months. Oh no, not unless you compensate me with some other in-game toy to play with.

I've mentioned before that back in the days of 24, a friend played in a 3e D&D campaign where an extended escape sequence was played out over weeks. To the DM's absolute credit, 4 of 5 players still probably recount it as their TTRPG highlight. So tense! My friend, however, was a low level Wizard.
