Brookhaven is free, but its game passes change how the game feels. Here is how the main ones compare.
Buy first: Premium (275 Robux)
Premium gives you the most for the money: premium houses, a helicopter, a private jet, a limousine and other vehicles, NPC companions, pools and vehicle recolouring. The helicopter alone makes getting around the map much faster.
Big upgrade: VIP Pack (999 Robux)
VIP includes everything in Premium and adds VIP houses and vehicles, two vehicles at once and no cooldown when you switch houses. It is worth it if you play Brookhaven a lot and like changing scenes during roleplay.
Cheap and fun: Horse Upgrade (99 Robux)
The cheapest pass that still changes how you play. It is a good pick if you like riding around town.
For housing fans: Land Unlocked and Estate Unlocked
Land Unlocked gives you more places to put a house. Estate Unlocked gives you the biggest homes. Choose the one that matches what you care about more: location or size.
Only if you want it: Music Unlocked, Disaster Pack
Music Unlocked is needed to play music IDs, but popular songs are often removed. The Disaster Pack is great for dramatic roleplay groups but adds little if you play solo.
Voldex also sells limited event passes during holidays. They disappear after the event, so decide quickly if one appeals to you.
