Speaking from my own experience, tired means your connection to the game is frayed. This is perilous, because if the game then upsets you, there's very little barrier preventing you from just leaving. If you're hanging on by a thread, that thread is easily snapped. And if you leave in an upset state, that upset remains, and keeps you away. I personally never seriously considered getting DF, and nothing they showed seemed anywhere close to mending my negative opinion of the game and its developers. If anything, it upset me more, as they weren't doing the things that would demonstrate contrition about what they had done.
