Mine was call of duty 4.

never 1k pointed a game, yet got almost 13k points >.< hate multiplayer achievements.

Can't say I ever have. The best I've got is about 800 in a game. Frankly I doubt I'll ever care enough to go for the last several achievements that always piss me off.

I've got about 5 or 6 sitting in the 700-800 mark, but i freakin' hate online achievements. That and I never really seem to go back and invest large amounts of time into one game - I tend to just buy new ones and play them instead.

Somewhat of a bad habit for the ol' Credit Card...

Sonics Ultimate Genesis Collection, the only game I have 1000/1000, usually do not have the patience to grind out those online achievements.  My college internet connection is horrible, making online achievements almost impossible to get while I am here. 

The last one was Fable in which I got 1100/1100 at long last thanks to a very nice guy online allowing me to witness his Doll Collector achievement. Right now I'm working on Afro Samurai And F.E.A.R. 2 - Project Origin. I might get all of Afro's, but I highly doubt I'll get all of F.E.A.R. 2's as it has a decent amount of online silly deathmatch oriented achievements and I rarely play online with people and even more rarely in a deathmatch scenario.

King Kong.......

Call of Duty 2, most games make me loose interest at around the 700-900 mark.

Dirt.  Getting the 1000 miles in career mode was super tedious.

 I think my last 1000 was Fight Night Round 3, but I am not sure.

SKATE 2

Technically I 1250-pointed my last one (Oblivion was it's name) and before that was Condemned:CO which only has 970 points so my last "pure" 1000 pointer was LEGO! Indiana Jones

NHL 2K6, then Call of Duty 2

Fable 2 or Gears 2, not sure which one I got last. Getting close on Fallout 3.

Last game I 1000/1000ed was Sonic's Ultimate Genesis Collection. It wasn't too hard and I only did it to unlock all the crap in-game.

I have only fully completed CoD4, but I'm at 950 for Gears 2 I think.

LOST Via Domus.

I'm a LOST super fan and man that game is terrible. 

In my case that would be Call of Duty World at War, really liked the game. Even if veteran dificulty made me break one of my two controllers (really, my LB button is no longer working).

Fable 2, but I don't think it'd count because I got 1000 with the DLC and not with all the original retail achievements.

Avatar lol

Spiderman: Friend or Foe.

But I recently came above 1000 points in both GTA 4 and Fable 2.

i just finished the Mage's Guild a couple days ago on Oblivion, 1250'd

Fallout 3.

Halo 3.

I have a Platinum in Burnout Paradise...

All 1250 in Oblivion. Before that all 1100 in Bioshock

Fallout 3

great game, easy 1000 points

"i just finished the Mage's Guild a couple days ago on Oblivion, 1250'd"

Open Season...but to retain any credibility, I'm one flag away from 1000-ing Assassin's Creed.

Oblivion. I got all 1250 in it.

Finished Seriously on Friday. 1250 in Gears of War now.

Prince of Persia. Very easy 1000.

The only game I got 1000/1000 (well, now it's 1250/1250) is Oblivion.  It's so easy, 'cause all you have to do is complete the story and all of the guilds.

I 1000 pointed in Tomb Raider: Legend (finally) but I've got Anniversary DL'd so there are still some points left to get

Avatar the last wind breaker, baby!

I takes 'em where I can gets 'em.

Skate 2

I don't play for GS...the only game I have ever 1000 pointed was Halo 3.

By Skate 2, I mean both of the DLC's too.  1250/1250

Hitman: Blood Money. For Sho.

Only hit 1k on 3 games... King Kong, Fight Night Round 3 and Lost Via Domus

I never 1000 pointed =(

I think it was Oblivion w/ the Shivering Isles package. 

I'm like two achievements away from 1000-pointing Assassin's Creed, but one of those is "Conversationalist", and I don't really feel up to playing through the story again.

I'm ashamed to say it but it was Lego Batman, the Lego games seem to be one of the few that my girlfriend enjoys playing with me.

Dead Space...like 3 weeks ago.

TMNT, terrible game.

I think my last was Lost: Via Domus if I'm not mistaking. I enjoyed that game though.
