Hello, I Think Catalyst Gaming should have 2 New Servers, A Terraria Server and a TTT Server,
For the Terraria server, i recommend TMod, right now there is only 1 VS That works, so your gonna have to use that, I Will upload it and put the link in here.
For TTT, You should probably have some Custom things, Such as, More Detective weapons, and more Traitor Weapons, Here are some i would suggest:
Traitor Weapons:
AWP - A 1 Hit, 1 Shot Sniper just for Traitors.
Turret - Plant it and let it kill innocents and detectives, doesn't shoot traitors.
Detective Weapons:
Golden gun - One Hits only Traitors, Detectives only, 1 Shot.
Defibrillators - Only Works on Innocents, Makes them back alive.
Also, Since you guys have a MC Server, you really should have a Terraria Server
