Why DarkRP & Starwars/Halo the only ones that seem to have a thriving community left

What is your take on the current situation of the game? Specifically, the game server list. It's not awful, but it's easy to notice options thinning.
Iis DarkRP the only normal RP gamemode that still seems to have a thriving community left? (no matter how toxic, massive by comparison.)
Why's DarkRP & Starwars/Halo the only one that seem have a thriving community left?
Don't get me wrong, I love all of these gamemodes... But I miss some of the ones that have disappeared from the server list. Aside from DarkRP,StarWarsRP, HaloRP and maybe even SCP-RP, all RP servers are non-existent or a ghost town.
I'm asking you why you seem to think the most direct reason for that would be? Open for discussion. Maybe we can fix the problem if we know it. Maybe we need to embrace new gamemodes as a community and share them when they have rewarding custom content.
Lord knows we're lacking a lot of that these days.

Don't believe me? Go here at anytime and tell me what you mostly see...... not just the DarkRP, you see the same 3-4 gamemodes repeating.
