Need some help understanding vesting period for this NFT game

Hi everyone, can someone explain to me what this means I’m brand new to NFT. About to invest in a NFT game but don’t understand why vesting period is. This is what they wrote about the vesting period of their tokens. Can someone explain all these to me in layman’s terms?
