1000/1000 Tales of vesperia made me proud ^^'.

Watch the credits - Can't remember what game.

But having to watch credits for an achievement was really hard.

I was pretty chuffed when I got 'Brass Balls', 'Little Sister Saviour' & 'Dealt With Every Little Sister' at the same time in Bioshock.

1000g on Ninja Gaiden II. Beat that!!

Completeing Lost Planet on Extreme condition was also unbeliveably hard. I'll be 950 forever as I don't have it in me to go through it on extreme mode again shooting all the targets.

Mongoose Mowdown Splatter an enemy with the mongoose in a ranked free for all playlist (Online).

Only because of how I got it. Someone shot a rocketlauncher near me and it launched me in the air and smack into someone standing on the bridge on High Ground.

Tankbusters Kill a Tank without it dealing any damage to a Survivor.

So so hard considering I didn't have any friends who played Left 4 Dead anymore when I did this.

Vidmaster Challenge: Endure In Firefight, on any mission, pass the 4th Set on 4-player Heroic LIVE co-op.

Probably the hardest achievment I've ever done due to how bad my friends are at halo. This took so so many tries, considering you often failed just a few waves short after spending 2hours+ getting to that wave.

There are some great achievements for me.

Guitar hero 3: Beat through the fire and flams in expert.
Gears of war: Kill 10 000 enemies online.
Mass Effect: up to level 60 and Beat the game in hardest mode.
Call of duty 4: Beat the game in veteran mode.

5 Achievemens than makes me proud.

Got all the achievements on ME2 - including most DLC that I've brought - Arrival, Shadow Broker and another one, I forgot.

100% on Red Dead Redemption? Those were some seriously grinding times.

Also finished COD4 on Veteran, but cos my profile was at friends house and I haven't gone online on my xbox, it didn't save the progress that I've made since I transferred my profile and didn't bring it back yet, so painful.

Back when I still had my 360, I was very proud to be at the number 1 spot for achievements (on MyGamerCard.Net) on Blue Dragon. There weren't a lot of 1000/1000 for that game and I was the fastest player to achieve them (below the 90 hour mark).

Of course, that almost costed me my 360 controller, mostly because of those Mario Party 1, Tug-O-War 1vs3 Difficulty level achievements (where you had to rotate your left analog stick fast enough to create a crater in the palm of your hand ), but it was so damn worth it XD.

Holy shitballs, now that is impressive! I tried and got to 700 G and then gave up. The 100% game completion one must've took ages.
