[quote:2iufx5x1]Sadly I still suck at promotion/marketing so its limited to a few posts on gaming forums and that's it. See how it goes, whether a good game can market itself or $$ for marketing is a must...
Even the best game won't sell if people don't know about it.
Having said that, personally I'm a bit wary of spending too much on marketing. We've tried it a few times - through a PR company and directly with major gaming sites - spending several thousand dollars each time and it's not really been worth it as we were lucky to break even.
I think the Kickstarter is definitely a good idea, but would suggest including some lower value pledges e.g. $1 = A thank you from the developer, $5 = A copy of Star Nomad 1, etc.
The best marketing we've had was being visible on Steam's front page, although that's post Greenlight and for us was mainly on initial release and releasing expansion packs so while "free" did take some work and persuasion with Steam. Opting into the Weeklong Deals and Recently Updated got some exposure/sales as well, so you could try those out for Star Nomad 1, which will also give exposure to Star Nomad 2.
Steam Curators are another way to get exposure. A kind word and a free Steam key to any relevant curator should hopefully get you a few reviews. One curator you might consider contacting is Space Game Junkie, you could give them a key for Star Nomad 1 and mention the Greenlight and Kickstarter campaigns for Star Nomad 2.
