Won't do that... besides, you don't want to reveal any good domain names in a public forum!
Look at your intended site, those of sites similar, and put the thinking cap on. I've sometimes found that talking with my friends about something I plan to put on the web they come up with good names just by hearing about it.
tangor's advice is spot on. If anyone posted a great domain idea - and it was available - there would be nothing to stop anyone from jumping ahead of you to register it.
I, personally, tend to favor generic descriptive domains that (hopefully) have a bit of built in (type-in) traffic as such domains save on "branding expense" (they're self-evident) and PPC expense (if they're good enough to gain type-in traffic).
I suggest you be forward thinking about the games business. Think "What's coming next" and think of domains that might describe "that". I'm not talking about trademarked names/domains, as in WidgetGameIV is "coming next". I'm talking about "the talk" of gamers, i.e., what new words are being made up right now, what new words/phrases might describe the next phase of gaming.
IF you can ever "coin the phrase", i.e., predetermine or "make up" the phrase that will describe a big trend (think OnlineGames.tld) . . well, chances are you will have a big advantage in marketing. ;)
Hi, I can suggest you that while choosing a domain for your website, you should have game in your domain name or a keyword that you want to searched for should be there in tour domain name, that will help a lot, like you can see here in <snip> they have <snip> keyword in domain that helps in ranking well in search engines.
