Topic: What's the best thing?

I'm talking about that feeling when you are playing video games that action/moment in a game that makes you happy/joyful when you finaly are able to do it:

Examples:
Ratchet and Clank FFA:
Sending 4 tanks to the enemy's base in multiplayer.
Being double teamed and still find a way to kill both.

Zombie Tycoon 2:
See your opponent running from a 46<Zombies Dead Rush

Call of Duty:
Getting one of those awesome Kill Streaks
Kill someone with a throwing Knife/Tomohawk

Uncharted 3 Multiplayer:
Using Juggernaut while you are under heavy fire in Hunter Arena Co-Op and kill them all without them knowing what's happening.
Roll Drop a Cluster grenade next to an enemy and survive all the grenades.
Break a lot of people's neck getting the assasin medal just make me smile.

Borderlands:
Ambush a Brute with a friend using both electrical weapons.
Getting a headshot with a in game sniper that doesn't have a sight.

Assassin's Creed 3:
Killing everyone inside a fort without getting detected.
Trick players with clones in multiplayer and immediatly stun them

Smash Bros Brawl:
Landing that amazing Link/Toon Link Final Smash.

Dead Rising 2: Off the Record:
Getting in a Zombie killing spree with the Blitzkrieg:

Well enough about me what about you.
What's the best thing for you in some video games?

In no particular order.

MGS2:
No detection run. INSANE stressful.

Killzone 3:
My brother and I taking on a team of 6 and still kicking their booty. HUGE kill streaks

Battlefield 2 Bad Company:
Not crashing a helicopter

GT5:
Getting my hands on the game after waiting YEARS.
Gold medals in the S.Vettel Challenges

RE5:
Staying up ALL NIGHT with my brother to finish our first run of the campaign on Professional. Those QTE........ I was heading back to college in the morning and we finished about an hour before I had to leave.. was intense.

PayDay: The Heist:
My friend and I finishing Diamond Heist on hard without a single guard killed. Also close, finishing Diamond Heist on hard and getting the MEGA diamond.

Monster Hunter Freedom Unite:
Too many to count.

PSO Ep 1 and 2:
FINALLY finishing Ultimate mode with my brother.

Aion:
Out DPSing everyone at a fort raid while using the absolute worst class in the game (ranger). What's nice is your name gets displayed to the entire server and the fort is captured in your guilds name.
Also, finally +10ing my stupid staff after spending HUGE amounts of time farming money to buy stones..
