orcishgamer: I know he didn't say anything about the original Prime, but he did mention Prime 2 which was a failure and an example of everything he seemed to be advocating rather than what he seemed to be making it out to be (some risky change that couldn't possibly have succeeded due to competition)...
orcishgamer: I only skipped around a bit, but that video basically seemed to argue that Prime 2 failed because it did a shitty job with the gameplay it was offering, not because the gameplay was similar to Half Life 2 or Halo 2.

They tried to tack on a Golden Eye style multiplayer and ignored the fact that everyone had already said "we're fucking bored of that" when they tried to push the exact same thing for Perfect Dark years before.

Metroid Prime 2 wasn't a copy of Halo, it was a bloody copy of Golden Eye/Perfect Dark, once again Nintendo trying to stick stubbornly to crap because "someone used to like it". Well, back in 1998 Golden Eye was pretty fun. But that was then, the gameplay hadn't aged all that well, and MS, Valve, and several other American companies had shown over and over again that not only was there a vast market for shooters, but the market existed on consoles as well, and offered multiple, successful examples of how to make one.

Nintendo did their own thing with online multiplayer, offered pretty much nothing interesting in the single player, and there's any question at all why Prime 2 didn't do well?

Yeah, I'm gonna have to go with the most likely option here, Prime 2 did poorly because it wasn't very good or interesting, not because there's some saturation point for "shooters" or something.

Elmofongo: I liked Prime 2 I think it was the strongest of the Prime sequals its kinda like this, I see the Prime Trilogy the same as the Godfather trilogy:

Prime 1/Godfather 1= Perfect

Prime 2/ Godfather 2= Very Good

Prime 3/ Godfather 3= OK but will never be as awesome as the older ones.

orcishgamer: I guess I'm glad you liked it, but speaking as someone who literally bought a GameCube in order to play Metroid Prime (literally went home with a Silver Cube and Metroid Prime), I not only hated it, I couldn't stand to play it for more than about an hour.

Elmofongo: You did not like the lock on system I take it?

orcishgamer: Actually it was the story that made me batty, as I recall, I couldn't give a crap by the time I was fighting whatever baddy on the loading dock to get off the ship or whatever (been awhile obviously). Nothing just ever got better for me, nothing seemed new, the whole thing was like I was just playing a level tacked on somewhere in the middle of Prime, which I dearly liked but drug on a hair too long imo. Getting more of the... well cruddier parts of Prime wasn't what I was hoping for out of Prime 2.
