I recently learned how to use これ, この, それ, その etc. but I was wondering how to introduce something new to someone, like これはゲームです and then adding onto that sentence to describe it (for example in English I could say “this is a game, it is new/fun/boring etc.”). I know I could use something like このゲームはおもしろいです but it seems like this implies the person I’m talking to already knows what a game is. Is there any way to introduce something new and describe it in the same sentence?
Thanks!
