"From now" versus "from now on"

[Sehanine]

Apologies if this has been brought up before or if it's a regional variation that I'm unaware of, but I noticed that the Sunrider games frequently use the phrase "from now" where I'd normally expect to see "from now on".  For example, "I'll be expecting you to work harder from now," versus "I'll be expecting you to work harder from now on".

Just curious.  Thanks!

This seems to be a common error(?) found in a lot of anime, vns, etc.
At least, in my experience.

The error is in saying "from now on" as you cannot terminate a clause in a preposition.

It doesn't matter if you end a sentence with a preposition.  I was wondering if it was regional variance because I'm used to hearing "from now on" but can't find any readily available info regarding it and it's jarring every time that I read "from now". With regard to grammar, "from now" is fine, as well.

Thanks!

Personally, I like "from here on out."
