Contest sounds fun and all, but whenever I randomly check out SC2 - there is never a Mafia game.
Once there was a lobby for with 1 player for 10 minutes before it disappeared.
Personally, I think it'd better that instead of having generic screenshots
(which are far less insightful on what the game is about in this game in particular) have them be themed and with big explanatory texts.
Like for example they have in this Arcade:
Not the greatest example of what I'm thinking of but it gets the idea across.
So like:
►Thumbnail1 = normal mafia logo with text on image "Similar to popular social deduction party game `Werewolf`"
►Thumbnail2 = screenshot of a chat with text on image "Catch someone in a lie or lie your way to victory"
►Thumbnail3 = regular screenshot with a red ring around the players role card and a text to go wit hit
►Thumbnail4 = regular screenshot with a red ring around where all the role cards are listed and a text to go with it
►Thumbnail5 = same for role list
