1. Rip Sprites.
Theres nothing worse than seeing a graphically stunning game, only to find out in the end credits "Sprites taken from www.spritearchive.com," or whatever. You'll be letting yourself down, and you'll feel that the game you've made isn't 100% yours. Only ever rip sprites if you cannot sprite AT ALL. And even then, try and learn from those sprites and don't acredit them as your own. People won't like that.<p>

2. Proclaim Your Game As "The Best Thing Ever"
This generally applies to newbies. Never, ever do that. I made the mistake when I joined the community of promoting my games. I thought they were great. But on seeing everyone elses games, I found that mine were at the bottom of the pile of pooh. You'll get shunned by the community. Instead, move to Point 3.<p>

3. Promote Continously

By all means promote your game. But don't over-do it. Don't spam every message-board telling people about your game and chucking in screenshots. Create websites with the game information on. E-mail administrators of major klik websites and ask them to put links up to your own site. When promoting your game, be tactful. Don't over-hype it. Instead, write on the website about what you have done to it so far, why you're making it, etc. Point out your achievements, but don't exaggerate. Don't say stuff like "This game will have a super, brilliantly done engine" - especially if you haven't even made the engine. Point out its shortcomings at the present and how you hope to overcome them.<p>

4. Become Bitchy

If you've made a finished game and released it into the community, expect mixed reactions to the game, especially if it's your first release. Take positive comments (things like "wow, that's a a great game! Really fun!") in your stride, take negative comments ("hmm, didn't really like this. The engine needs work") as constructive critism, and retarded comments ("teH GeAm SUXXORRSSS!11") as complete ignorance. But, whatever you do, if people don't like your game, never insult them ("well, it's better than anything you could do") = it's NOT. These people have been in the community for a long while. They understand what makes a good game good and a bad game bad. Instead of insulting them with a retort, just listen to their comments, go back to the drawing board and start again, this time trying to work on what made the people say these negative comments.
