Like, MegaMan was always my favorite game series growing up, and I looked forward to each of the games released. Eventually this spilled over into the MegaMan X series, and the same carried on. Eventually, when the games got to the 32-Bit era with MM8, MMX4, MMX5, MMX6, they started to rapidly become a weaker incarnation of their former selves. But because I was a big MegaMan fan, I felt compelled to buy them anyway. And I did, until MegaMan X6, which, to this day, I’ve played a total of 30 minutes of and never touched again. I own MegaMan X8. I don’t think I’ve ever even opened it.
Same with the Contra series. I love me some Contra games, but, you know, Neo Contra wasn’t all THAT great, and Alien Wars on the GBA is a horribly botched version of the SNES game, and Shattered Soldier sometimes makes me want to kill small woodland creatures. But I own them all anyway. And, hell, if I could find Contra Force, C: The Contra Adventure and Legacy of War, I’ve probably get them too, even though they literally killed the franchise at one point.
And, dammit, SOMEONE out there must still be buying the Sonic games, even though they’ve gone from great to good, to okay, to fair, to poor, to crap, to horrible, to depressing, to abysmal.
