The first game that truly got me hooked on gaming was the original Age of Empires. The lengths I would go just to play that game still makes me question my sanity...
Rewind the clock a few years... (Ok, maybe a little more than a few). My dad gave me an old HP laptop that was from the late 90s running Windows 95, a processor that had less clock speed than a bottle of water, and just enough hard drive space to squeeze the OS and maybe one or two low-end games. The screen was no more than 7 inches and it had one of those pop-out mice attached by a flimsy piece of plastic. It didn't even have an integrated CD-ROM drive! The only option I had was a battery powered (Yes, that's right, 6 AA batteries!) LPT CD-ROM drive that lasted all of about 10 minutes at max speed before the batteries went dead. If I even wanted to install the game, I had to do extra chores for an entire week just so I could go and buy the batteries required to power it. I had my house, my backyard, and front yard looking pristine just so I afford the batteries to play what may have been an hours worth of that damned game.
Looking back, it was all worth it, as gaming has been a big part of my life ever since and I wouldn't trade a second of it for anything.
