#14) Sonic & Knuckles (GEN/SAT/GCN/PS2/Xbox/Wii/X360)
Aside from the anticlimactic battle with the second titular character, this game is just great. Through and through, from top to bottom. Nothing stands out because everything stands out.
#13) Metroid Prime 2: Echoes (GCN/Wii)
Black sheep, my ass. This game has everything a Metroid game should have. Difficulty, mood-setting music, giNORMOUS bosses, and tension in spades. It's also nice that you actually have to conserve ammunition and switch between weapons instead of just mowing through everything with the Plasma Beam. On some days, I might even say I like it more than the original. But those are days when I don't remember that grueling scavenger hunt near the end, and they are not common.
