Providing games-related services is a simple and potentially efficient way to earn your first bitcoins.
I whish I was a gamer myself so I could do the same.
Good luck and welcome in the bitcoin economy.
Maybe you don't need to be a gamer yourself to do that.
There are quite a few games available for free that we could add Bitcoin support to, currently my bottleneck in actually checking out such games and getting players in the test them to make sure they actually work is the hosting, so in addition to doing promotional work such as directing traffic to game sites or getting game banners displayed all over the net etc there is also potential to actually invest in game projects that need funds to get hosting.
Currently for example I am using a free hosting account to test (and, it turns out, debug and fix up) Xnova Redesigned at http://galaxies.mygamesonline.org/
That free hosting account only allows one MySQL database so although it has enough disk space left that I could upload a Travian clone to test, it would not provide another database, which the Travian clone would need.
Mos games out there don't let you buy and sell their stuff, nor run bots. So I am checking out all the free open source games I can find and would like to set up instances of all of them that work, all modified to accept bitcoin. I have quite a bit already done but that means I have pretty much used up all the hosting I have available...
The more people actually put bitcoins into such games of course, the faster I will be able to expand my hosting to permit more games to be set up and checked out.
