Geeze... just look at PBW. There are more than 30 active players of SE4 there. Then consider that PBW represents but a small fraction of the player base... Sure there is not a whole lot of
posting about the game going on, but that doesn't mean noone is
playing it.
Why do you say that S1st considers SE4 to be a non-seller? They still
have it listed for sale.
