the games that defined my childhood are as such.
Space Quest II: Vohaul's Revenge (Apple IIGS) - This was my first computer game when I was 4 years old and helped teach me to type and read, as well as use a computer. It was funny, challenging and, at the time the graphics blew my mind in comparison to the Atari 2600 which we had as kids.
Altered Beast (Sega Genesis) - When my older brothers pooled their money together to grab a genesis with Altered Beast packed in, my day was made. This was the only game for the system that we had for the longest time and the co-op play made it worth it. I still can play through this game blindfolded. I know the contours of this game more than I do my wife..........
Teenage Mutant Ninja Turtles (Arcade) - The one that got away. I was an arcade child during the rise of fighting games and beat-em-ups on the scene and TMNT was the game to play. I remember playing with my older brothers, getting to shredder before we ran out of cash. We had $20 between the three of us and we got all the way there. Luckily, when we bowed out, some of the onlookers picked up the mantel and finished it after us. We didn't get the glory of victory, but at least we saw the end.
Combat! (Atari 2600) - Another game that took up a lifetime of entertainment amidst my brother sand I and continued to fuel the competitive spirit that I hold today. All of my friends and family played this game religiously, taking the gameplay to another level of art. The planes, moving in an arial ballet of awesome. So much fun!
MYST (PC) - The game that scared the crap out of me as a kid. My aunt and uncle purchased it for us and included a printed out guide. When seeing Sirrus and Achenar in those books, as a kid I was very disturbed. It inspired me though and intrigued me, fueling the curiosity to explore far more than any other game. The impact of this game is a great influence on how I view games as an artform, crafting vivid worlds to explore and detail that exists, yet holds no impact on the story or gameplay, one of the most important facets that I feel games CAN have.
