How to Find New Opponents
Many gamers are looking for new opponents. This is nothing new. When I was a teenager, there were maybe four war gamers in Amarillo that I knew, but there must have been more as the one store that carried Avalon Hill games (then the only wargames) would sell one or two now and then that my friends and I knew we didn't buy. Funny, it never once occurred to us to ask the store manager to give our phone numbers to the other guys. When I was in college, SPI (then the second wargame company and rapidly becoming larger and more innovative than Avalon Hill) had an opponent wanted list. I sent in my dollar to get it, and found only one person (of the 20 on the list) who was within 120 miles; the first and last person on the list were each 450 miles away (in opposite directions).
These days, the concept of contacting other gamers has had decades to mature, works much better, and there are a lot of ways to do it. For best results, you should do all of them.
If you play Federation Commander, then you can go to the Commander's Circle and enter your data (as much or as little as you are comfortable with) and perhaps find opponents near you. We are gaining new sign-ins every day, and since it's free you can try it every month or two and find out if somebody nearby has signed in. http://www.starfleetgames.com/federation/Commanders%20Circle/
Primarily for Federation Commander players, the Forum has a topic where local stores and groups post announcements and invitations. Players can let other players know they're around. How silly would you feel if you found out that the guy who you've been arguing with on the forum for years actually lives in your town. (That HAS happened.) http://www.federationcommander.com/phpBB2
You can to go to a local store and ask them to let you post a notice looking for opponents. You could also run a demo of your favorite game(s) and "grow your own" opponents. If a person already plays the game you are demoing, he'll doubtless drop by just to swap phone numbers.
Many towns have community bulletin boards on the local cable company's "home" channel. These are variously free or cost just a couple of dollars. It's hit-and-miss, but you could get lucky. (When I commanded Company C of the 1-39 MPs, I gained a dozen new recruits in a year that came from cable TV.) You could also buy a cheap want ad in the newspaper or the free advertising newspaper (American's Want Ads or whatever yours is called) found in quickie marts. There is also Craigslist, but you should use the normal caution you would for meeting a stranger.
The quickest result, probably, is Starlist. Go to http://starfleetgames.com/starlist.shtml. Enter your data in the form, and you'll get a list of local players back. (This may take a day or two as it is done by hand.) Starlist is the most effective hunt for new players because the database has some 5,000 players in it, far more than all of the other sources combined. The only drawback is that Starlist works with full information (name and address) and those who are seriously concerned about identity theft often find this uncomfortable. In all reality, however, Starlist would not give an identity thief any more information than a local phone book would, and if that's enough for those criminals to operate, they would be vastly more likely to use the phone book than to request a copy of Starlist.
You can find opponents for all of our games on our BBS. Go to http://www.starfleetgames.com/discus/ and you'll see "Seeking Opponents" on the main menu. You can post a notice there (and search the previous postings). Again, you can post as much or as little information as you are comfortable with.
Friends of our page on Facebook can post to see who is out there. Not a friend? Become one here: http://www.facebook.com/pages/Amarillo-Design-Bureau-Inc/231728653279?ref=mf
With more effort, you can post opponent wanted notices in a whole lot of boardgame sites (see http://www.starfleetgames.com/links.shtml for suggestions).
If there is a game convention within driving distance, it's worth a trip to see if you might find someone who is also within driving distance. If there is a game club in your home town or a store with a gaming area, go there and set up the game and wait for somebody to ask what it is. (Even better, take a friend who will play the game with you so you won't be bored.) If there is a Star Trek club in your home town, show them Federation Commander or Star Fleet Battle Force. There are people who have printed a card with the logo of one of our games and their email address and left these in the windows of their cars who got emails from other gamers in their home towns who were seeking opponents.
You can go always go to SFB Online (http://www.sfbonline.com/index.jsp) and play Star Fleet Battles and Federation Commander online with live opponents from around the world for the princely sum of $5 per month. You might even stumble into somebody local.
There are probably more ways than this to find opponents, but unless you live in a cave somewhere, you can almost certainly find a new friend within a short while by trying these methods.
