We've all had these moments - Moments that only occur when you accomplish something that's very hard in a video game. For instance, completing MegaMan 2 is a ridiculous, but you've pushed through to the end. Beating Super Mario Bros. without warps is also pretty damn tricky, but you've gone and done it.

So, in this thread, you post your proud moments of video gaming. Whether it be 100% a game, or doing an ordinary part of a game with a challenge to hinder you. [NO SPOILERS KTHNX]

Here are my most recent ones:
You probably know that Sonic 4 Episode 1 is a pretty easy game. Well, that is until you try getting the achievements on the XBLA version. Splash Hill Zone Act 1 in under a minute? Piece of cake. Collect EVERY ring in Special Stage 1 AND finish it? That's pretty damn tricky. I spent at least an hour trying to do that. SUCCESS!

I showed a whole community of Modern Warfare Players that Rank does NOT Equal skill.So I went killing off the whole bulk of them, while resetting my stats so I was only Level 1. They Banned me but at least I got my message through to them.

I just spent a few hours playing 30 songs in LEGO Rock Band. It wasn't hard at all, with the exception of Constant Motion all the songs were very easy. But it did take a bloody long time >_>

Achievement unlocked
Endless Shameless - 50G

EDIT: I found my Kirby Super Star Ultra game and beat Marx Soul (Final boss battle). This isn't like a walk in the park like with Bowser or Tabuu. (Yes, I called Tabuu a walk in the park. ) You have to get through 9 other tough bosses and the only means of recovering HP is a couple tomatoes that only heal less than a fourth of your HP. The only way I beat Marx is to have the Stone ability and turn into a stone for the whole battle, and slamming into him when he's near the ground. (Dashing torwards him then pressing B)

Me and one of my best friends killed General RAAM in Gears of War 1 on Insane, in 37 seconds.

DID THAT JUST HAPPEN?!

Beat SMB without warps or death, beat level 3 on the Unfair Platformer.

I'm a huge Guitar Hero fan, so I already had 49/50 achievements on Guitar Hero II. The last achievement left to get was Millionaire Pair - Score 1,000,000 points on a single song on Co-op. With anyone who could play on hard well, this would've been easy, but unfortunately I was stuck with my little brother, who'd pretty much perfected medium. I was on expert, so to get more points I played rhythm while he played lead (Lots of chords in rhythm). We'd tried countless times over the past few months to get this achievement, each time we failed it just made my brother not want to play even more. This morning I convinced him to come out and play with me, and guess what?! On our third try, we got 1,003,000 points. That was so close! We jumped around and screamed in joy!

Just did this a few minutes ago in Hitman Blood Money

Not only did I get 100% accuracy, but all the shots were kills.

Though I'm not sure why there were so many witnesses. I made sure that nobody saw my kills.
