Hardcore gaf, I come to you once more for advice!
Been listening to a lot of Rhapsody (emerald sword saga mostly), Korpiklaani, Blind Guardian (Nightfall in middle-earth, dear fucking god what I've been missing) and I'm itching for more.
I still do not know how to classify this genre, is it progressive metal? Whatever it is it's what I need at the moment

Any suggestions on big hits/awesome albums I should know about?
I'll chime in on this one mainly because I can never resist. Everyone else have given great suggestions but here we go.
If you want something in the vein of Rhapsody (over the top power metal), I suggest:
Dark Moor - Hall of Olden Dreams
Heavenly - Dust to Dust
Elvenking - Heathenreel
Power Quest - Master of Illusion
Sonata Arctica - Ecliptica (more Finnish synth driven, but they rule anyways)
If you want something more like Blind Guardian (riffy power metal):
Hibria - Defying the Rules
Gamma Ray - Land of the Free
Helloween - Better than Raw
Grave Digger - Excalibur
Primal Fear - Seven Seals
Angra - Temple of Shadows
Aaaaand Korpiklaani (folk metal):
Eluveitie - Spirit
Metsatoll - Aio
Skyclad - Prince of the Poverty Line
Wuthering Heights - Far From the Maddening Crowd
Tyr - By the Light of the Northern Star
Also, for the dude that wanted something in the vein of Black metal, but also suggested Nightwish I'll suggest Moonsorrow. Not because they sound like Nightwish at all, but because they are a folk/black metal band with a lot of melody. Awesome.
