Yes, but after DMC 2 I think it was in even worse of a position then DMC 1 had been. Also, sales data for 3 does not include the SE copies, so its impossible to know how much higher then the shown amount the real number is (granted, the boost is under 1 million or we'd know that number).
DMC 2 was apparently very damaging to the player base. It was my proper jumping on point, so I don't really get it myself. --- "Ware wa Sanger Sombold. Aku o Tatsu Tsurugi Nagi!" The last thing Evil hears before it is Cleaved in two.
