Well, first of all you'd need a program to make it in, and learn the coding that makes it work... I suggest you look around in this forum section or try google for some tutorials.
Unless you mean a boardgame or something. Then you just need a good idea and the ability to execute it with text and illustrations.
If you mean a Flash game, you will probably need Flash, I'm not into the other freeware programs for making Flash games
Flash has an easy to use interface on animation, so you might wanna try that first, since it comes with its own lessons
After that, you want to make a game and not just an animation, you'll need programming, which on Flash is Action Script
We're in the middle of the transition, from Action Script 2.0 to 3.0, so in theory it would be better to learn 3.0, but it wouldn't do you any good if you find it too hard and quited it, so there isn't much trouble if you prefer to start with 2.0
There's really no easy way into game programming, you just need to look for the codes for moving, coliding, etc. The Flash Help file is useful, but we actually lack a newbie tutorial
As mentioned before, it all depends on which program you want to use.
I suppose it's the same for each program though... toy around a bit with it, learn how to use it. Also, after/during that, you can google some tutorials... for most applications there will be some sort of 'easy game' tutorial, so you can get started.
It all comes down to increasing your knowledge of the program and the programming language used with it.
well, it only took me a week to know how to make games in flash (flash is t best way to create games for me), I DO know how to make games but it is really hard to make a GOOD game, If you make a bad one everyone will go like, "boo you suck",or, "Why da hell do you make games?". I am practicing my skills and hopefully I will be able to make good games ui the future, One thing you really would need to pratice is your flash rawing skills, start drawing something simple like a tree, then do a whole scenery, I remember seeing a flash video called the big fat tutorial, But I dont remember where it was.

Everyone's start is ugly. Even experienced programmers such as John had a few early games that he probably now would consider to embarrassing to reveal to the public.
You learn from what you do, weather it's good or bad, and each time you make a program, it gets better, so even if people complain, keep improving, and learn from their criticism.
One thing you really would need to practice is your flash drawing skills
And one helpful reminder that I have found looks nice is Gradients. Even something as small and simple as changing the background from white to a white/gray gradient makes a huge difference in how professional the game looks. Just don't over do it!
