Lol, I know. or even the Metroid Primes. Consiering they share the same aspect of huge elaborate maps.
And yet, we still have things like Castlevania 64... And after it's failure, (Symphony was merely a side game to 64's "main current gen castlevania") they decided to go with what works, and gave IGA full reign over the series. after which we got all metroivanias.
then eventually, they tried to tackle 3D again, and came out with Lament. I guess it did alright enough to warrant Curse of Darkness, but they were both rather unimpressive. Fun, but unimpressive and meh.
And so once again, the aversion to 3D came back. And Cox comes in, and proves that you CAN make an amazing 3Dvania.
