its dead. it didn't have many grindy issues but the major problem with suburbia was that anyone who loads into the game first has the greatest advantage so there's no point ever playing it because there's 10 people on the server who have had the time to build their boom empires
the problem is that everyone gets too big of a head and doesn't know how to stop feature creep
it wasnt feature creep, all the mechanics were meaningful. gyt and you were trying to overthrow base raiders and their solutions involved some backwards ass bullstuff which ended up being slightly worse than base raiders
feature creep is basically adding jobs and drugs into cityrpg because 'why not'. suburbia didnt get any feature creep until they started designing weapon tiers and expanding the gui beyond what was capable. also people will play suburbia to kill and build bases because that's what the game was designed around, while in cityrpg the game is designed against killing people, as it essentially punishes you harshly and sends you into a downward spiral of demerits which ruin your life in general.
