So, how do you come up with a game idea?
Really it does.
What genre do you like?
Not so interested in RPG as it's way too much work, and not interested in Puzzle because I don't have the sheer patience to play most of the time.
Platformers are cool, but like RPGs, I suspect it'll be way too much.
(my byline from the Gamedev Collection series, which I co-edited) John Hattan has been working steadily in the casual game-space since the TRS-80 days and professionally since 1990. After seeing his small-format games turned down for what turned out to be Tandy's last PC release, he took them independent, eventually releasing them as several discount game-packs through a couple of publishers. The packs are actually still available on store-shelves, although you'll need a keen eye to find them nowadays. He continues to work in the casual game-space as an independent developer, largely working on games in Flash for his website, The Code Zone (www.thecodezone.com). His current scheme is to distribute his games virally on various web-portals and widget platforms. In addition, John writes weekly product reviews and blogs (over ten years old) for www.gamedev.net from his home office where he lives with his wife and daughter in their home in the woods near Lake Grapevine in Texas.
A couple of friends and I made something along these lines... A Tetris game that featured backgrounds that are generated and pulse to your own MP3's. (Shameless plug: btw, check it out and some other simple games at: http://www.deadiguana.com)
However, if you are beyond the simple game stage or just want to do something a little more original, just let your mind wander for a little bit.
For example: What about a ginger-bread man? You start out as a simple doughy bread man, and have to run and jump, collect sprinkles and other adornments on your way to the cookie sheet. You must dodge frying pans and the occasional crap crusted on the stove.
The world needs more unique game ideas, in my opinion. Just try to think of something that you know you can complete, and give it a go. It doesn't hurt to use exising game ideas, but be sure to bring your own unique elements to the game, and not just, "Sims 2, but they can have sex!"
What about a game about Alfred the Goat? He has psychological problems and dreams of being swallowed whole by cottage cheese curds. (Yuck). In order to pay for professional counselling, he has to eat weeds out of a garden.
Just sit down and let you mind wander and I'm sure you'll come up with something. I believe in you! :-)
And just throw ideas, crazy ideas, combining genres, until you hit a good one. ie Shot em up Survival Horror Puzzle Simulation (Not a good one, but you get the point)
Use your imagination.
SSHPS (Shot em up Survival Horror Puzzle Simulation) WTF?...hehe
Even if it's a game being made totally from scratch, it should be one that I'd want to play, if I want to respect the artform.
I had an idea for a game I'd like to play that was born off from the fun I had with Battlezone and how bland Battlezone 2 felt, but it would have been too much work to make. I think programming it and seeing everything come to life probably would have meant more than the actual play value. I may never know.
