Still yes, because MP3 was not designed quite like the typical Metroid game. I think the FPS elements, and the fact that a lot of the backtracking was stripped out, could have made it a reasonably big success if it had been advertised properly. Not that I want that to happen or support the linearization of Metroid, but from a marketability standpoint it's a pretty unfortunate missed opportunity. Besides, the Metroid fanbase is large enough that it could have a shitty marketing campaign and still sell reasonably well. Which it did.
This really isn't the kind of place to talk about gameplay, but Corruption had no chance to appeal to any casual FPS fan that wasn't already into Metroid. Despite the control scheme, Corruption didn't have that much more of a focus on combat than the other two Primes did. Yeah sure there were some precise targets, but the enemies weren't smarter. It still didn't trump the exploration element of the game. In fact, one could argue that the combat is more Metroid oriented in Corruption. No more contrived beam switching like in Prime. They don't force combat down your throat to the detriment of exploration like in Echoes. The few FPS qualities Corruption does have aren't the point of the game like it would be in an FPS. FPS games are primarily about combat. Forward progress is marked by eliminating clusters of enemies (with a focus on AI hopefully) using a vast arsenal of guns and weapons. Most of the time you don't even have to engage in combat in Corruption, and when you do, the focus isn't on eliminating enemies: it's on completing an objective with enemies as a nuisance. Your beam is your main weapon. The enemies aren't terribly smart.
Technically, all Metroid games are linear in one sense of the word (with the exception of the first). Unless you sequence break, there is one set path for you to go down in order to complete the game. It does create an open ended world to explore, which certainly gives you a sense that the world really is non linear. Corruption didn't remove backtracking. You still have to go back and forth plenty of times (I shouldn't have to name them all). What Corruption does is make the path more obvious. Where as in Prime you have this huge world and might not always know where to go, Corruption tends to make things more obvious by making all other paths closed off due to not having the item needed (although there are plenty of exceptions). That is not the same thing as you're saying.
But Corruption as its heart is not conducive for the casual market. It relies on heavy atmosphere, level design, boss battles that are more puzzle oriented, and combat that isn't exactly of the FPS breed. It can be argued that Corruption is easier to figure out for a casual because it has been streamlined a bit, but Metroid can't hide what it is. If people want a more casual experience, there are a hundred shooters that are better designed for that. Metroid Prime got some casual exposure. It didn't stick. The series just isn't built for that, and it's too late to really do anything about that now. Unless Corruption truly betrayed the Metroid lineage (which it didn't do), then there was no hope for it to reach beyond its hardcore audience either. And that's okay. That's how the series should be.
