I haven't played a great deal of Golf 2600, but I had a lot of fun the times I did play.
According to my txt file of high scores the best I've done is a 47. On a par 36 course.
So clearly I'm not very good at the game, but it's still a lot of fun.
The only thing that's baffling at first is how to aim. It's a little wonky, but a quick read of the manual remedies that.
I don't like the real life game of golf. If I want to play a dexterity game I'll play Darts or Crokinole. Crokinole is an amazing game. Party favorite. Everyone who has ever played it loves it. And it takes up a small part of the dining room table. Not a hundred acres of prime real estate and millions of gallons of water.
But I do enjoy arcade style golf games like Golf 2600 and Golf on the Game Boy, stuff like that. It's a good casual, fun, laid back time.
I think an updated Golf 2600 would make a great choice for a homebrew project. I mean, there's only two moving objects on the screen, the player, and the ball. A programmer could focus on having many different courses to choose from, a refined aiming mechanic, better graphics, etc. Golf was a 2K game. Imagine the possibilities with a 32K game.
It seems like it would be one of the easier projects to undertake, and one that would provide a tremendous amount of game play and replayability, assuming one could pack in a ton of courses. Golf has 9 holes. What if an updated version had 45 holes in 5 courses, each course selectable from the start menu (like a SpiceWare game).
It's too easy for me to start fantasizing about this sort of thing...
