So, as a general rule, we all encounter problems at one point or another in video games and on the systems. So, by general rule, we sometimes ask our friends for help; rare as it is now, considering that the super sophisticated games are easier to figure out than, say, Metroid on the NES.
But nonetheless. Sometimes gamer's need help, even now. You might not even be stuck somewhere, you may be asking how to do a glitch, the quickest way to the top of a building for a Metroid Speedrun, or even the best way to avoid conflicts with Dragons in Skyrim. Suggestions are great things to post, also.
And inquiries don't have to be limited to the games themselves. It could be about the system you play these games on, as well. Maybe ask the people here about how you can report suspicious or malicious activity on your respective system's internet service, best way to fix the Red Ring of Death, or how to extend your DS or PSP's battery life tenfold.
There are many resources on the internet, yes; but sometimes we just can't find them. So, feel free to help your fellow gamers with whatever advice you can give.
