Answer 1

ビデオゲームはとてもたのしいだから。
I was informed that だ from だから was the wrong verb conjugation in this sentence.
What would the right way to say this be?

Answer 2

Would it make sense to change it to this?
ビデオゲームはとてもたのしいから,します。

Answer 3

Or this?
ビデオゲームはとてもたのしいだから,します。

Answer 4

In general, you end a causative clause by ですから.
I would write:
とてもたのしいですから、私はよくビデオゲームをします。
But I am not a native speaker.

Answer 5

Oh. Alright. I didn't know that. Thank you for informing me. ^^

Answer 6

だ　is needed to end a clause in the neutral speech with nouns or な-adjectives only.

がくせいです　→　がくせいだ : I am a student
じょうずです　→　じょうずだ　: I/you/he is good at...

whereas い-adjectives do not use だ at all:

たかいです　→　たかい　 it's expensive
たのしいです　→　たのしい it's amusing
