Metroid Prime 3 isn't that bad, compared to some other titles...& Prime 1&2 completed,
Although it's a bitch to emulate.
The Hunters game for the DS is like a Prime-lite game.
Still better than Other M. Or the horrible Marine spin-off game with chibi-styled characters."Samus Returns" thing, but it looks 10 times more popamole than aM2r.
I respect/second omitting Prime 3. It's definitely a lesser experience than 1 and 2. AM2R was the perfect victory lap to roundout a playthrough of the series.
Metroid Prime 3 isn't difficult to emulate at all. I think the problem is that a lot of people just don't take the time to set it up properly. It runs perfectly in Dolphin now, but to get the best experience, you need to use a Wiimote.
It's absolutely worth it too. I strongly disagree that any Metroid fan should skip it.
I think the one where you fight the evil copy of yourself is my fave. Pretty sure that's also the one that has a weirdly well executed jumpscare for a little GBA game -- at some point you're exploring some messed up scifi labs and a big fucking silhouette of a monster flies by in the background. Got me, anyway.
I always thought it was strange that Nintendo made two different Metroid games where you fight an evil copy of yourself. You're talking about Metroid Fusion, but Metroid Prime 2: Echoes uses the same premise.
