I always had an idea for a sort of LCS remake, but as a forum game and revolving around music. Instead of the Liberal Crime Squad, you're the Disco Squad, and trying to bring about the revival of disco. Other factions include the Rockstar Alliance, Dubstep Brigade, Classical Symphonists, Country Crew, and a bunch of other rival music-themed squads I haven't thought of yet. Like a name for a jazz-focused squad.
At the start of the game, Disco is dead. Very dead, in fact. Very few people like it, and thus very few people are willing to join up for the cause other than your founder and a small group of other friends, depending on starting choices. You must make Disco the most liked genre in the country by committing crimes in the name of disco, going out in public and blasting disco music, kidnapping anyone who doesn't like Disco and brainwashing them, musical activism, etc. You must also survive, since music is very serious business, and the other groups will do whatever it takes to make their musical genre the most liked in the country, even if it involves violence.
In addition to the rival music squads, there's also the police and the general public to deal with, too! Tolerance for "musical violence" is very low at the beginning, since people killing each other over not liking Rock and Roll is insane and shocking. As the conflict escalates, the public eventually gets desensitized to all the violence. Be careful, however, as too much violence will backfire and possibly lead to a full-blown civil war and the country being balkanized or something. The police won't exactly tolerate violence and crimes, either, unless bribed to look the other way.
