Spoken Vietnamese is tonal (like Chinese). For example, you can form several different words with "ba" via variations in tone and accent marks. One misspoken tone changes the meaning of a word.

It is a fun language to speak, read, and write. Also, it is great for people who want to learn an Asian language without having to learn a completely different writing system.

I figured it was tonal from the way it was written, plus the fact that you said it's more like Chinese than Japanese (although Japanese can be tonal, almost.. it's a matter of knowing how to pronounce it, and then how lond to hold the sound for, I guess..).

And there is that.. though part of the reason I like Japanese so much is the way it's written! :D
