Is it true that all game ideas suck?

I recently read this: http://www.escapistmagazine.com/articles/view/issu...

I have no experience in game development, and I'm wondering if an idea thought of by someone who has no experience in game development would actually work. I've been writing an idea for a game on notepad for about 2 weeks. I'm trying to think of about every detail, such as the story, the controls, the level design, what NPCS say, etc. I'm even trying to write songs on the piano for the game for fun. I don't ever expect my game idea to be made, I'm kind of just doing this whole thing for fun. I believe it's original, and I don't see any flaws with it.

Do all games ideas suck? Every single one? I find this hard to believe. I've played lots of video games, so I feel like writing an idea with no flaws shouldn't be that hard. Sure, there are flaws like a key conflicting with another one, or maybe no possible way to get to the next level or anything, but there are also flaws like something in the game not even being possible, or the game being too laggy.

Even though I don't know anything about game development, I disagree with the person who wrote that. I could be entirely wrong.

So, like I asked before, do all game ideas actually suck?
