Seeing the graphics on Monkey Island 2. I was wowed by the game.
Intro to Shadow Of The Beast 2 on the Amiga, even today this day it still looks and sounds good! Settlers and Syndicate had me wowed for an intro too
Seeing the intro to the game Worms on the playstation 1. My jaw dropped and I wanted one straight away
Pandemonium graphics on the Playstation 1, although it was a shitty 2d platormer, it was in an 3D world, the graphics were colourful and quite spectacular
I had played various split screen games before (Lotus 3 and various racing games) but going around a friends to play the Goldeneye with a 4 player split screen was a magnificent feeling of excitement, I was pinching myself could it get any better than this? I had no idea what it would be like and was completely blown away (mostly buy a rocket launcher)
I don't play games like I used to, but recently downloaded a game for Android (I think it's on Xbox and Apple products too) it's called Limbo, a dark platformer/puzzle game. I was in awe of the graphics and the tone.
Some people have mentioned Tomb Raider and I 100% agree. I was mesmorised through most of the game, the art work, the tombs, the size of the game, and the little snippets of music they chucked in now and again just made it beautiful. I think it was either level 4 or 5 where you're surrounded in some tombs with orange walls made me feel like I was going back to ancient times. People would probably laugh at all the polygons and her triangle tits now, but I played it about 5 years ago on the PSP and it was still a brilliant game
