Joking a side treat it like anything else you are trying to get someone involved. Show them the game. When I worked at comic/gaming store in south florida (horrible area to game) demo games where standard. But what sold them the game was the hobby and story behind it. If you try and sell the game as just a wargame people will be well.. i dont like risk or ill just play risk so why play this. keep in mind it can be an expensive hobby too so dont ask your college buddy with 2 part time jobs.. he will just feel bad that he cant afford plastic figurines or action figures (thats what normal people that i know call my collection). OH, and let them win at first. Always let them win until they know the game.
To recruit new players you have to find a pool of people who might be interested. Look for gamers any type of gamer, artists (drawers painters etc) and hobbiers.
Id say start at a gaming store but ... im hoping you already tried that. Call all the gaming stores in your city and ask. At your school look for any gaming clubs hobby clubs or w/e. Post flyers that interested in starting one or just post
40k player new to the area looking for fun. etc.
You will find players but it depends on the effort you put in,
TBH. Start at stores then your school. If all else fails try greigs list.
lol.
