Your biggest wow moment of each gen you've lived through

[Scoobes]

As I primarily game on PC the gens get a bit blurred for me, but the moments that stick out:

SNES: Super Mario World- I'd never played a platformer that controlled so smoothly
PC: Doom- First time playing a first-person 3D game was mind-blowing
GB: Zelda: Link's Awakening- The realisation that they'd managed to cram such a huge game world into a hand-held.

PS1: FFVII- The opening of FFVII and the narrative thread that ran through all of Midgar made me realise the storytelling potential of games.
PC: Half-Life- The opening again completely changed the way storytelling in FPS' worked whilst the AI actually seemed believable, especially for the time.

PS2: Metal Gear Solid 3- The ending was an emotional roller-coaster
PC: Deus Ex- Realising the sheer number of ways I could complete each level and complete tasks in hub areas.

PS3: Uncharted 2- The level with the helicopter and the collapsing building whilst fighting. First time in a game I'd experienced anything like it.
PC: Oblivion- Not sure when but at some point during my main playthrough I just felt like I could find myself living in Cyrodil
Mass Effect 2- The suicide mission and the way the whole game inter-weaved and lead up to that point

PS4: Uncharted 4- the ending was perfect
PC- Witcher 3- Just... everything. Completely raised the bar for wRPGs.
