Quoted from CrazyLevi:

You are trying to sell a Time Warp - one of the worst and least desirable or sought-after pinball machines of all time - with heavy playfield wear, a shitty backglass, and display and other "minor issues" for $1,100. That's why it's getting no attention, not because the bubble is bursting. Your friend on Facebook is experiencing the same issue. The market for Time Warps has never been "hard," therefore, it cannot "soften."
Price that game appropriately - $600 obo - and you might notice an uptick in action on your ad. That's an optimistic "might" as you'll still be trying to sell a beater Time Warp, and that's just not on too many folks' Christmas list.
As far as the rest of the market...it's always best to wait before making "bubble burst" proclamations:
