Hi, my name's David, I've been making flash games under the banner Melloland Games (link) since 2009 and getting them sponsored on FGL.com. The flash market is steadily going down though so I wanted to publish my next game for mobile (android/ios) and maybe pc too. The thing is, I suck at marketing and getting the word out there. I've read some articles that say you should get a list of hundreds of gaming websites and reviewers and contact them each individually about your game, and I don't want to sound lazy (although to be fair, I am) but it sounds like a huge waste of time, especially if only 1% of them actually take you seriously.

Other than that, I do have some specific questions;

1. Do I need a website dedicated to my game or will a simple page on my website suffice?
2. Are press release services an alternative to contacting countless gaming sites and reviewers by hand?
3. If I just HAVE to contact hundreds of people, I assume I want them to play my game, so should I give them a full version of the game or is a demo enough?
4. Is it better to look for a publisher or distributing the game yourself?
