ok. . . lets get some things straight lol
a name is just that. . . a name . . . it doesn't need to be relevant. . .. it doesn't even really need to make sense.
If a buisness/site is successful, people will rarely question the name and accept it as it is. . . .
for example. . .google. . . . i mean. . what the hell?. . .. thats a stupid name. . . . but it isn't seen as that because its got immense popularity. . . . same with amazon. . . . the word itslf has nothing to do with shopping what-so-ever, but we all accept it because its an established brand,
so thats bassicly just saying, ANY name can work as long as its short and simple.
the only real requirements are just that. . .. make sure its short, simple and rememberable ( to an extent)
Ask Jeeves has recently changed its homepage and operating title to simply "ASK".com.

easier to remember for sure lol.
being related to your topic MIGHT help, but an abstract but simple name might stand out more and be more rememberable to a user. . . .
i.e, what stands out more. . .
www.gamerbase.com
www.GammingHQ.com
www.gamepad.com
www.Gamingworld.com
or
www.Crave.com/.net
i know what would stick in my mind more once i had visited the site. . . . as long as you market the site properly getting people to recognise your site as related to gaming wouldnt be a problem. .. . .
hope my thoughts have helped (or possibly confused)
