Garrett, I'm Slipping! I thought about the topic for a while. There have been so many games that rocked my world since I began gaming that a whole list would probably be too long to post. What I'm really glad about is that it continues to happen. I'm always a little worried that the day will come when no new game is able to knock my socks off, since I've seen and done so much already.
A little selection:
Asteroids (Atari 2600): The first game I had the chance to extensivly play. The fascination that
I control what happens on a TV screen was enough to start my gaming career.
Alter Ego (C64) A whole human life (told mostly in text form) simulated from birth to death. This game still holds a lot of fascination for me, even if the theories it is based upon are a little stale. (
Browser/App version)
Sim City (C64) There's a whole city in my computer! The C64 version was ugly and very abstract, with colored squares as buildings, but I didn't know better.
Frontier - Elite 2 (Amiga) The sheer scope of the universe in this game left me devastated.
Ultima 5 - Warriors of Destiny (Amiga) The first Ultima game I owned. I never played through, but the detail of the world simulation was mindblowing at that time.
Turrican 2 (Amiga) For me still the pinnacle of the 2D run'n'gun platformer. Perfection.
Doom I was there. I was afraid. And then I beat it over and over.
Quake My first real MP experience was Quake shareware. To think you are connected to other human players from all over the world...
Planescape: Torment Well. Was is there to say. Revealing yet another strange piece of the Nameless' past and seeing how it all fits together and makes sense (Circle of Zerthimon anyone?) just to see it all crumbling down and rearranging with the next discovery...
Deus Ex I have to add, I played this for the first time after 9/11, with all that war going on, all the theories about "what really happened", omnipresent surveillance and anti-terror laws like Patriot Act being established all around the world. The game left me with a strange feeling quite a few times.
Morrowind The moment I realized that strange and alien land I entered weeks ago suddenly feels like home.
The Chronicles of Riddick - Escape from Butcher Bay The first game that really conveyed the feeling that I'm the most badass character around and the enemies are actually afraid of me.
System Shock 2 For scaring me when I thought that wouldn't be possible anymore.
Bioshock Would you kindly not spoil it. Also: Armin Shimerman's voice work.
Operation Flashpoint For being the most non-heroic and deadly approach to (half-)modern grunt warfare in an open world where things play out differently each time. I've never been bathed in sweat like with this one.
Stacking While it's a small game and can be a little repetetive, many details are just hilarious and funny. And it oozes love from every corner.
Skyrim I call it hiking landscape simulator. I can wander this beautiful land for hours and not get bored. It's not the same like Morrowind - I don't feel as much "at home". But it's like going on a vacation to Scandinavia (+ dragons). And yes, the dragons. While too easy to defeat (yes, mods, I know) I was just blown away when one landed heavily on the roottop right above me for the first time.
Have to stop here, lest there be coming another hundred entries. I could talk about the final battle in Freespace or Aerith dying in FF7 or the unlimited possibilities of Master of Magic or, or, or...
