Do you think Metroid (Prime) is a hard series?

[Shanobi]

Yeah, it's a hard series. Emporer Ing in MP2 was insanely hard. I'd say harder than the final boss in MP1, though they both took many tries to beat. I don't remember dark Samus giving me too much hassle after Emporer Ing, though.

I can't even remember the boss to MP3, so it must not have been that much trouble. The giant golem with the orbs was kind of a pain at first.
