A well-run company with a pr team or even just an exploited PR person on a starting salary can drum up anticipation and excitement for the game on Social media. Heck the developers could do it even but let them concentrate on the game.
The PR person can basically for free (apart from his internal salary) post on social media, be funny gain a following for the page, respond to the community in a direct informal way. Send PR articles to gaming websites, and traditional media so that your game is "featured" for free as you make the media think there is a scope for news there, they can even ride Popular culture opinions on social media to become trending and gain followers, Even the smallest of companies can find tremendous marketing success with a smart PR person, capable of gauging public option and trends. Its not that hard, if they give me admin access to the social media channels of Rugby Challenge 4 then I will work wonders with their online presence in a matter of weeks.
You can create, newsletters and tease the public with in-game player ratings e.g Farrel has 90 tacklings, 90 indiscipline, AWJ has 95 leadership. Kolbe has 95 Stepping. Build up the highest-rated players announcements much like Fifa does on you social media platforms. Try and collaborate with popular social media channels to feature your page in exchange for something with little to no financial value such as mutual exposure or credits.
You can think out narratives such as " we have a team of so many woman developers" or "We are trying to put rugby games on the map again by promoting green practises in our company while developing" Media jumps on this **** and its free.
And why not over hype the game. If it allows us to sell more copies and you make more money to improve the game actually instead of absorbing the money and not using it for further development.
Send editors and journalists of Tv stations and magazines in a country by country basis clips, images and a free copy of the game.
If you have a small marketing budget then Target the geographical areas with specific campaigns. set your demographical age targeting on social media, what areas you want to target, what income groups, what age.
If they run social media ads in SA, then feature pro Springbok ads, to 15 to 38 year old mostly men. In England target that age group but put special emphasis on the private schooling system, make funny targeted posts about Itjoje and Farrel, have a bit of banter and rip Wales or something.
In the Welsh,campaign climb on the AWJ bandwagon and rip Ireland or whoever the Welsh likes to rip, in an hour i can do enough research to find this out.
Try and entice legends of the game by sending them game footage of you recreating certain things they did in real life, maybe they share it to their thousands of followers.
I can continue with a full marketing and PR plan for these companies, its not that hard, you need to play the real-world game in this modern era. Also,a good PR person makes a lot of journalist buddies, and this can do very favourable things for your ratings...
I get that these small developers also need to make money, so can't just reinvest their profits back into development, and that's probably why small developers have not brought us the game we want since Rugby 08.
