Hello,

I am in the process of completing a browser based multi-player social game, with a space theme. I'm wondering if anyone has any experience with marketing and can give me some good suggestions on where to advertise to get players. I have around a $1000 initial budget to spend on marketing.

I would suggest advertising on social network sites like facebook

If its an MMO you should contact sites like MMOHut to get them to review your game. If not, then like mmarkzen said, try to advertise on sites like Facebook, Twitter etc. You should also look for forums or sites that are based around the genre that your game is and tell people on that forum about your game to try to get them interested in it.
