I've written from scratch a browser based strategy game. The game involves registering a "planet", developing it, building an army/navy/air force and attacking other planets, killing their troops and stealing their resources. It's written in PHP and is 100% unique. I've built in a premium membership option, so players can subscribe via paypal for premium membership and pay $10/month for better upgrades, money etc within the game. I have no budget to market this at the moment and I'm way too busy to market it for free. If I was to sell it, finished but not launched for the public, how much do you think it'd be worth? You can get a preview of it here, its on my test site - http://www.mikey1090.com/pz/index.php
