Help with nft collections contracts

Hello guys i would like to create 3 NFT collections and every nft will be unique and can only have 1 owner. Each collection should have 10k nfts. I would like to use the ERC1155 cuz i want to add more fungibe/nonfungible tokens and dont want to create smart contracts for every token. but if i used ERC1155 i would needed to create 30k items with a supply of 1?? If its like that then id rather use the ERC721. All the nft collections are related to together cuz its a nft game. Could i create one ERC721 smart contract that will have 3 nft collections ?? Thank you guys
