multitudinous - many
Something ‘multitudinous’ consists of many people, things, or parts. Strictly speaking, this word expresses something infinite or countless, but is mostly used as a more formal way of saying that there is an awful lot of something, or simply as an exaggeration to make a point or show emphasis.

I don’t believe in micromanagement or placing restrictions on staff. I much prefer there to be a multitudinous flow of ideas and opinions.
