Owned Met for some years (left after deciding TWD won out for Borg, center bash/magnet toy games). Have had BSD for 4.5 years and it's "bolted to the floor." IMDN for 1 year.

Would rate them BSD>MET>IMDN, but they're all great games and I miss MET at times (never the same on location).

I've gushed plenty over BSD in the past, but the short version, aside from it being the greatest adrenaline rush (partially due to the ramping volume/intensity), is that it equates to Tetris for me in the sense it's simple to understand, yet challenging, and always exciting to beat your previous best score (unlike some games where score seems secondary to mode progression). The simplicity becomes a strength in never getting old, as opposed to a mode based game with a wizard mode that may feel "beaten" once you get to the end.
