Games I've Played
Mostly Shooters and Stuff
- Mass Effect 3 Multiplayer
 - Halo: Combat Evolved
            Legendary solo
I really liked Halo: CE. It was a strong game, and I've had a soft spot for the Halo story - I don't think it's particularly deep or told with finesse, but it's fun!
 - Halo 2
            Heroic co-op
I've been telling myself I'm going to beat Halo 2 on legendary by myself since the day I beat Halo: CE on legendary. I feel the overwhelming urge to be able to say I've beaten the whole trilogy on the hardest difficulty! On the other hand, it's really goddamn hard.
 - Halo 3
            Legendary co-op Legendary solo All Skulls found
 - Halo 3: ODST
            Heroic co-op
 - Halo: Reach
            Heroic co-op
 - Gears of War
            Insane co-op
 - Gears of War 2
            Hardcore co-op
 - Gears of War 3
            Hardcore co-op
 - Half-Life
 - Half-Life: Blue Shift
 - Half-Life: Opposing Force
 - Half-Life 2 (and Episode 1) (and Episode 2)
 - Portal
 - Portal 2 (and co-op)
 - Army of Two
 - Army of Two: 40th Day
 - Operation Flashpoint: Dragon Rising
            Gave up after like 30 minutes
This game was terrible.
 - Resistance: Fall of Man
            Hard? co-op
 - Resistance 3
            Hard co-op
These games weren't very deep, but they had decent shooting and good weapons. Resistance 2 didn't have co-op, so I didn't play it - I just watched my friend do it.
 - Killzone 3
            Veteran? co-op
This game offered alternate color modes for colorblindness, which is awesome. Shame the dialogue and plot was so literally laughable.
 - Resident Evil 5
            Veteran? co-op Broke one level
My pal and I played this over one break, and we couldn't take it seriously. Once we beat it, we spent our hard-earned points on getting infinite ammo for a few weapons - and decided we'd try to unlock infinite ammo for every weapon. We didn't end up doing that, but we did get so practiced at going through one level - which drops the most money for the time you spend in it by far - that we beat the max difficulty time trial by half. The magnum in that game is ridiculously overpowered.
 - F.3.A.R.
            Fearless? co-op
As far as I can tell, these people have no idea what the phrase "survival horror" even means.
 
Not Shooters
- Pokemon: Red
            Beat the Elite Four
 - Pokemon: Silver
 - Pokemon: Diamond
            Beat the Elite Four
 - Prince of Persia: Sands of Time
 - Prince of Persia (2008)
 - Super Smash Brothers: Melee
            Every SP challenge
 - Super Smash Brothers: Brawl
            Every achievement except one sticker
 - Mario Kart: Double Dash
            Time Trial Staff Ghosts Every Cup on Mirror
 - Mario Kart: Wii
            Gold Medals on Everything
 - Okami
            All brush techniques
 - Legend of Zelda: Link's Awakening
            
I think this might be my #1 pick for best Zelda game.
 - Legend of Zelda: Ocarina of Time
 - Legend of Zelda: Twilight Princess
 - Super Mario 64
 - Super Mario Sunshine
 - Final Fantasy
 - Final Fantasy 6
            Halfway
 - Final Fantasy 7
            Halfway
 - Final Fantasy 8
            Halfway
I feel like including Final Fantasy games that I haven't finished is still reasonable because not finishing a Final Fantasy game involves a similar time commitment as finishing many other games.

 - No More Heroes 2: Desperate Struggle
            Mild

            Expert

Extremely Memorable
- Shadow of the Colossus
            Hard Time Trials (Normal) Climbed the temple
I love this game so much I'm not even going to write about it. My thoughts would take up too much space.
 - Ico
            
Ico was very pretty, and had some of the same quality that Shadow of the Colossus had, but it didn't tie together nearly so well.
 - Mirror's Edge
            Easy Test of Faith (Pacifist)
This game has the best platforming I've had the pleasure of experiencing - and I'm a sucker for good platforming.
 - El Shaddai
            Normal
I loved this game from an aesthetic point of view, but I kept waiting for the story to get interesting. I'm still waiting.
 - Zeno Clash
            
The aesthetic really makes this game stand out.
 - Iji
            Normal Somewhat Pacifist
Iji remains one of my favorite games of all time, for its excellent pseudo-morality system - one of the best I've seen.
 - Valkyrie Chronicles
            Normal No deaths
Valkyrie Chronicles had such a cool gameplay and storytelling style that I have to include it.
 - No More Heroes
            Mild All Beam Katanas
It's hard to describe this game. It was fascinating.
 - Elite Beat Agents
            Sweatin'! Hard ROCK!
Probably my favorite rhythm game.
