#20) Ratchet & Clank: Up Your Arsenal (PS2)
This right here is my favorite thing to ever come out of the 3D platformer genre. It's funny and action-packed, controls like a charm, has even more ridiculously disproportionate weapons than the first two... Hell, even the 2D Captain Qwark mini-game and the shoehorned multiplayer mode are fun. If it were as long as Going Commando, it would break the top 10 in a second.
#19) Super Castlevania IV (SNES/Wii)
Remember when Castlevania games... Hell, any games had music like this? I don't, because I wasn't alive back then.
Thank God for the Virtual Console.
#18) Sonic the Hedgehog 3 (GEN/PC/DS/Wii/X360/PS3)
What it lacks in the amount of Zones, Sonic 3 makes up in level length and complexity. Marble Garden, Carnival Night and Launch Base are just huge compared to every Zone seen before in the series. (Except for maybe some stages in Sonic CD) Furthermore, the special stages don't make me nauseous or swear profusely at my sidekick, which is nice.
