- drop the name. It's too similar to a popular game, and the differences will draw ire, not applause, from that crowd. And it sounds in concept dangerously close to Supremacy.
- Don't bother trying to find a buyer. You'll need to go it yourself to build enough rep to get someone to by it from you.
- Best bet: PDF playtest. Do a low-cost PDF Print & Play version, counters and maps both printable. Get people to play it, critique it, tear it apart. Then revise and re-release based upon their feedback.
- Once you have it playtested, use a Kickstarter project to raise the up-front money for the initial print run. If you get enough, you print. If not, you don't, but you aren't out anything (and Kickstarter kicks back much of the cash.) See below for more on this.
- Once you've raised the cash for the initial print, you do the initial print run. IMMEDIATELY fulfill the kickstarter promises. Then sell the rest through a website, and offer stores and distributors a discount.
When you go to do the kickstarter, remember to account for printing costs, component costs (the bits can probably be commercially acquired), and your combining time and effort, and at inventory tax for your locality for at least a year, plus shipping and handling on the absolute worst case of owed copies due to the kickstarter. Plus 25%, as (IIRC) Kickstarter takes 20% off the top.
So, if your "$5" is a revised PDF of to match the last minute changes in the boxed set, that's pretty much a freebie. If it's going to cost $30 in parts and print, and 10 minutes to pack, that's 0.15 hours, and you should pay yourself $10/hr for pack, so $1.50 for that, and $30 to ship anywhere in the world can be done... you need to set the "get a signed copy" at about the $100 level... so that, even if EVERY bit of your initial run of 200 is eaten, you still are getting in $80 per set costing you $35 to make and up to $30 to ship.
And no matter how you do it, get ads out. A column inch in X-men is frightful expensive, but is an advert that will be seen for years and around the globe. An advert in your local paper is forgotten the next week, and seen by only a tiny portion of the target audience.
Don't neglect conventions, either. People playing it in a demo are likely to spread word of it... good or bad, it's a great route for feedback.
