I've also tinkered around with an Apple II emulator. Apple II games were my first forays into heavy gaming until we bought our NES in 89 or 90.
I've been trying to get my kids into the emulator games, but with their DSes and iPods, Minecraft, they just don't seem to be interested. I get bored with some of the games, too.
Did you notice how difficult the games were? Not actually gameplay, but if you died...you started over (for the most part). I'm used to instant (or nearly instant) respawns in modern FPS, where you might have to wait 10 seconds to start off where you died.
I used to play a board game RPG called Car Wars. Basically, it was Mad Max and Dungeons and Dragons. The Apple II had a game called Autoduel, which was based on the Car Wars world. You scavenge an armored car, build a character, and run convoys or become a mercenary to earn money. Great, great board game...but the video game was unbearably difficult. You start with little money, and you have to enter in gladiator-type contests to win money to begin the game...but you get killed so easily in the gladiator "pits" that it isn't much fun. Then you start over at $0.
The Apple II sports games were great, though. Winter Games, Summer Games, and my personal favorite, Superstar Ice Hockey:http://www.whatisthe2gs.apple2.org.za/s ... ice-hockey
