I was born in 1977 in a country far far away where sand dunes were my playgrounds and 100 degree weather was mild and pleasant. I started gaming at the young age of 3 (I have pictures to prove it lol) when my dad bought an Atari 2600 for us to play. I grew up playing that Atari more than anything else in the home, much to my mother's dismay. She claims that after a while, the Atari had me so mesmerized that I wouldn't even step away to eat so she used to make milk, sugar and egg shakes for me to drink while I was playing and apparently I drank them happily to get her to leave me alone. My favorite games on that machine were Kaboom, Breakout, Pitfall, Space Invaders, Combat, Missile Attack and River Rapids.
As a closing note, my favorite games of all time are, in no particular order:
Capitalism II - My favorite economy sim of all time. Very old but very deep. I recommend this to anyone who wants to learn the basics of business and economy. Its much better than a book especially if you grind into the details. Not 100% accurate and there are a few bugs (especially in the stock market system), but good fun if you ever want to build a business empire and dominate all other corporations to become a monopoly.
Galactic Civilizations II - Easily and by far my favorite civilization building game. I have spent hundreds of hours playing this game and it never gets old. I even created my own set of ships some resembling an old anime that I loved back when I was a child (Grendizer). Its also made by a very pro-player company in Stardock. Check them out if you don't know who they are.
Honorable Mentions: Diablo I (didn't like D2 very much), Warcraft II, Starcraft, Anno (they are all the same), Civilizations (all are fairly good), SimCity (except the latest 2013 which I uninstalled after a day), Dragon Age, Mass Effect, Fallout (all of them are great), FFIV, FFV, FFVII & FFVIII (everything after that I found boring and gimmicky), Half Life, Guild Wars 2, Leage of Legends, Heavy Gears II, KotOR I & II (incredible games), Neverwinter Nights I & II (though II was very buggy), Sacred, Titan Quest, Skyrim, Forza (love them all), Dungeon Keeper 2 (cant wait for the new one), Plants vs Zombies, Defense Grid, & Tropico 3.
