That's fantastic! You've more or less nailed it. I've taken a look at my set, which I've tweaked a couple of times for balance, and the only real differences I see:
- Weapons
- 2x Gas Grenade, 5x Tranquilizer Darts (since they work in multiple weapons)
- Items
- 5x First Aid Kit, 5x Keyring
- Vehicles
- 3x Kawasaki Golf Cart
- Locations
- 2x Security Bunker, 2x Supply Bunker, 2x Holding Pen (I like more dinosaur variety), 3x Steam Tunnel (the mechanic adds variety to play)
