Yeah I love me some gaming. Bought a house yesterday and just got a new 36in Sony Bravia and new Samsung surround sound for my game room. AWESOME. Gotta say love my wife to death for letting me have on of the 3 bedrooms all for myself and make it the ultimate guys/gameroom. Painted Atlanta Thrashers with my jerseys on the wall, shelves with all my gaming stuff and all. Cant wait.

1. Metroid Prime 1
2. Prince of Persia SOT

I hardly ever beat games. I think I beat like 1 of every 10 games in my collection.

This year I've beaten:

Tales of Symphonia 2
Timesplitters 2
Star Parodier
Flower
Rag Doll Kung Fu

Killzone 2

@Senor Says
How is Symphonia 2? I never played any of the Tales games, and it's unfortunately not available to rent.

Resident Evil 5, Resistance: Fall of Man, Resistance 2, Flower, Noby Noby Boy, & Linger In Shadows.

*Resident Evil: Umbrella Chronicles (finally)
*Kingdom Hearts: RE Chain of Memories (Riku's story too)
*Hotel Dusk: Room 215 (my 2nd time, but I got the Good Ending, yays!)
*Elite Beat Agents (on Easy; stuck on Jumpin' Jack Flash on Normal)
*Guitar Hero I, II, and Rock the 80s (I got the 3-pack for Christmas)

And I'm working on 5 other games that cover DS, PS2 and GCN. Will update when I stand on top of their defeated forms.

Tales of Symphonia
Super Paper Mario
Dragon Quest IV: The Chapters of the Chosen
New Super Mario Bros.
Meteos
Pokemon Red
Pokemon Fire Red
Pokemon Sapphire
Pikmin

I'm trying to complete my back catalogue rather than succumb to spending too much money on new games. I have quite a lot that are a work in progress, so there are several half-completed games that I can add to that list soon, hopefully!

That's actually one of the games I'm working on! I got stuck on Jumpin' Jack Flash on Cruisin' as well, but if you stick at it, everything clicks eventually. There are more difficulties to follow, mind, I still haven't completed the 4th one!

Pokemon Platinum
Pokemon Diamond(twice)
Pokemon XD (again)
Elite Beat Agents (easy mode)
Super Smash Bros Brawl(Adventure mode)
............and yeah, that's about it.

SSMB twice

New Super Mario Bros (Beat It Again with 3 stars)
Namco Museum Remix (twice)
Super Mario 64 ds (10+)
Mario Kart DS 150cc Mirror Mode

I have a list of more games that i beat over and over and over again.

That Includes All of my ds games except Nintendogs, brain age 1 and 2, and big brain academy. 15-4

• Phoenix Wright 1, 2, 3
• The World Ends with You (ha, knew I forgot something)

... i'm probably still forgetting something, though. that's gonna bug me. :/

Really this should be a list of games beaten for the first time, or for the first time on 100%, good ending, super fudhe brownie in 2009.
@theblackdragon-Speaking oh Phoenix Wright, I go through the whole series twice a year.Probably beat No.1 6-8 times and the others just afew times less each with Apollo probably seeing 3 playthroughs...I love those games. I'm playing through Rise From the Ashes, which I consider separate from PW1...it's also my least favorite case...

Punch out Wii

I know there was one more game that I've beaten for the first time but I can't remember it
but yeah it's been pretty retro for me this year.

@Objection_Blaster: I liked Rise from the Ashes because it really showcased what improvements they were able to make with the DS as opposed to the ported GBA episodes (and in retrospect, it helped to flesh Ema's character out considerably, though not so much where she picked up the Snackoo habit, and Gumshoe got some good airtime as well). Storywise, though, it's not really my favorite either. They did their best to fit it in, but it still felt odd to play through the previous three episodes with Maya and then to not see hide nor hair of her in that 'last' case. It also didn't get a splash image for the episode-choosing screen, IIRC, which helped to make it stand out from the others worse.

1) Chrono Trigger (DS)
2) Resident Evil 5
3) Halo Wars ( Was pretty meh...)
4) Mega Man 2
5) Yoshi's Island
6) Crash Bandicoot 2
7) Killzone 2

And I'm sure theres a few more but I really can't think of any...

Adam you beat Mother 3 isn't that import only and only in Japanese?

Yes, but there is an English translation patch made by fans for the ROM.

NOT THAT I USE EMULATION BECAUSE THAT'S ILLEGAL

Right?

@Adam

...Riiight... But when Ninty won't show you some love... You gotta get your Mother fix somehow!

And as my job is testing games for a company I cannot mention because of NDA agreements... I've beaten too many games to count on both Wii (my home console) and another next-gen this year already.
