この is a determiner, so it must come before a noun. Here it modifies 協力型ゲーム.

• この協力型ゲーム = this cooperative-style game
• これ = this one / this thing

So you can say:

• この協力型ゲームは... = This cooperative-style game is...
• これは... = This is...

But you cannot use この by itself.

協力 means cooperation or cooperative play.

型 means type, style, or form when used as a suffix. So 協力型 means something like:

• cooperative-type
• cooperative-style

So 協力型ゲーム is a game of the cooperative type, meaning a game where players work together rather than compete against each other.

は marks the topic of the sentence. It tells you what the sentence is about.

So:

• この協力型ゲームは = As for this cooperative-style game, ...

The rest of the sentence says something about that topic.

A learner may wonder about が, but は is natural here because the sentence is presenting a general statement about the game. Using が would change the nuance and often sound more like identifying or emphasizing the subject.

Because 楽しい is an い-adjective, and in Japanese, an い-adjective comes directly before the noun it modifies.

So:

• 楽しいボードゲーム = a fun board game

This works much like English adjective + noun order.

Other examples:

• おもしろい本 = an interesting book
• 大きい犬 = a big dog

The main predicate is 楽しいボードゲームだ.

The structure is:

• この協力型ゲームは = topic
• 楽しいボードゲームだ = what is being said about it

So the sentence is literally structured like:

• This cooperative-style game
  • is a fun board game

The final だ is what makes ボードゲーム into the predicate: is a board game.

だ is the plain-form copula. It is the casual or neutral equivalent of is in sentences like this.

So:

• 楽しいボードゲームだ = is a fun board game

In polite speech, you would usually use です instead:

• この協力型ゲームは楽しいボードゲームです。

Both are grammatical. だ sounds more plain, casual, or written-style.

Yes. That would mean This cooperative-style game is fun.

The original sentence says more specifically that it is a fun board game, so ボードゲームだ classifies what kind of thing it is.

Compare:

• この協力型ゲームは楽しい。 = This cooperative-style game is fun.
• この協力型ゲームは楽しいボードゲームだ。 = This cooperative-style game is a fun board game.

The second sentence gives both a description and a category.

Yes. In this sentence, 楽しい modifies ボードゲーム, so together they form a noun phrase:

• 楽しいボードゲーム = a fun board game

Then だ attaches to that whole noun phrase to make the predicate.

So it is not:

• This cooperative game is fun, board game is...

It is:

• This cooperative game is [a fun board game].

Yes, it sounds somewhat repetitive in English, but it is still perfectly natural in Japanese.

The first ゲーム is part of the topic noun:

• この協力型ゲーム = this cooperative-style game

The second ゲーム is inside the predicate noun:

• 楽しいボードゲームだ = is a fun board game

Japanese often allows this kind of repetition more comfortably than English does. In natural context, a speaker might also choose a less repetitive version, but this sentence is grammatically fine.

No. Japanese is normally written without spaces.

So the standard writing would be:

この協力型ゲームは楽しいボードゲームだ。

The spaces are often added only in teaching materials to help beginners see the parts of the sentence more clearly.

In normal interpretation, この modifies the whole noun phrase that follows, which is 協力型ゲーム.

So the meaning is:

• this [cooperative-style game]

not:

• this cooperative-type, game...

In Japanese, この comes before the noun phrase it determines, and here the noun phrase is 協力型ゲーム.

The sentence follows this pattern:

[noun phrase + は] [adjective + noun] + だ

More specifically:

• この協力型ゲーム = noun phrase
• は = topic marker
• 楽しいボードゲーム = adjective + noun
• だ = copula

So the overall structure is:

• As for this cooperative-style game, it is a fun board game.

This is a very common Japanese sentence pattern: topic first, then a description or identification.
