In the contract `GameServerNftBaseV1`, the role `GAME_SERVER_ADMIN` has authority over the functions shown in the diagram below. Any compromise to the `GAME_SERVER_ADMIN` account may allow the hacker to take advantage of this authority and update token metadata, as well as mint NFT with metadata URI internally.  In the contract `GameServerNftBaseV1`, the role `GAME_SERVER_SUPER_ADMIN` has authority over the functions shown in the diagram below. Any compromise to the `GAME_SERVER_SUPER_ADMIN` account may allow the hacker to take advantage of this authority and mint NFTs, set token URI, and update token metadata URI. 

In the contract `GameServerNFTBaseV1`, the role `admin` has the authority to update the implementation contract behind the proxy contract contract. Any compromise to the `admin` account may allow a hacker to take advantage of this authority and change the implementation contract which is pointed by proxy and therefore execute potential malicious functionality in the implementation contract.

While not a requirement, generally each upgradeable contract contains 50 storage slots in total, including already used storage slots. In the `GameServerNftBaseV1` contract, the total number of storage slots used exceeds the common convention for upgradeable contracts. Specifically, the contract uses 2 storage slots for state variables and reserves an additional 50 storage slots using the `__gap` variable, bringing the total to 52 storage slots. This exceeds the typical convention of reserving a total of 50 storage slots, including used and reserved slots, which may lead to issues in future upgrades if not managed carefully.
