Games I have that are rare and awesome:
Ikaruga - Legendary shmup, played for weeks just so I could beat it on normal, then have put it away since. Still pull it out every time people complain that games today are too easy (they are, but there's still the occasional gem that makes you throw the controller in its difficulty)
Super Mario RPG - Flippin' awesome, man. I picked this up in a lucky find at a friend's house, since they were cleaning out everything in order to pay off debts. One of the best RPGs I've ever played.
Mega Man X3 Probably my favorite X-series game (admittedly, I like all of 'em equally, so what does it for me is the music. I could hum Volt Catfish all day)
Games I have that are awesome (one per console):
Too many to count, but a few:
Jet Force Gemini - Mostly unknown shooter from Rareware for the N64, awesome shootouts and some oddball humor. (blowing up bugs en-masse at the rave party was awesome)
Super Smash Bros. Brawl - Can't wait until the tier lists come out for this thing. (of course, they probably already have and I don't know but hey!)
F-Zero GX - So !@#$ing hard, so !@#$ing awesome. This game always feels like you're ten steps behind with how fast it is.
Skies of Arcadia - One of the few major contenders to the Final Fantasy series, in my opinion. This game deserved at least a spiritual sequel. Probably its only major flaw was the obvious plot decisions and the overuse of cliches, but YOU COMMANDER A GIGANTIC FRIGGIN' PROTOTYPE SHIP AND FIGHT OFF ENTIRE ARMADAS IN THE SKY WHO CARES ABOUT PROBLEMS.
Gunstar Heroes - One of very few reasonable answers to Contra back in the 16-bit era, this was brutal and awesome. Always played with lightning + fire or force + speed if I was lazy.
Kid Chameleon - Naming two for Genesis because I've played more stuff on it than on anything else. This game is one of the best platformers I've ever played. It was simple to pick up and ungodly difficult to finish. The Final Marathon is the hardest platforming stage I've played in any game, ever, though Bloody Swamp runs a close second. (unless you count I Wanna Be The Guy, which was meant to be stupid)
Kirby Super Star - Legendary. The only really, seriously easy game that I love to play over and over and over. Revenge of Meta Knight and Milky Wishes = <3
