When I finally do what I've been trying to do for a hour!

Entering Mexico in Red Dead

Just finished this one...

Favorite game moment? Hmmm. Rough one again. Let's seeeeeee... thinks
That moment you finish Dark Souls?
Oh crap, I haven't done that yet D:

I actually have no idea. There are so many moments that were great. Can't really think of a favorite one.

Baldurs Gate final with Ascension mod (just thinking about it gives me chills)
Saints Row IV - When Haddaway kicks in, during ship escape
Dark Souls - basically every boss fight xD
XCOM EU&2 - Shotgun killcams
I can go on, if You'd like to xD

Honestly I have no idea, can't think of one. I enjoyed waaay too many moments in games to list. But I did like the MGS5: Phantom Pain's intro c:

Not sure if it's my favorite but it's up there and what came to mind first...

My favorite moment, i'm not sure. Some that comes to my mind:
Skies of Arcadia,when you get the ship upgrade to go above/below the clouds and be free to explore the world at your own pace.
Almost the whole Citadel dlc from Mass Effect 3.
The intro of Metal Gear Solid 4.
Beginning of Resident Evil 2, the way to the police station.

Tomb Raider, Midas' hand death. =)

Every time I used bullet time in Max Payne games.

this intro was so epic and perfect.

Hmm.... maybe the WYK reveal from Bioshock? It's been a while since I played a really cool game. :(

The end of a great game and the beginning of something special Crisis Core Ending

Thanks jbond :)

This is a toughie, but one of the first one I thought of was this.
Maybe not for the best reasons? But I love it haha.

Dragon Age Origins Battle at Ostagar (i love this game). Thanks for the chance!
