Like I said in my Ape Escape review, this version was actually the first one I experienced, and while the conversion is not perfect, I think it is a perfectly fine way to play the original game.

In some aspects, I actually prefer it over the PS1 original, as I'd rather mash the button corresponding to the gadget I want to use, rather than rotate the stick.

With this one, I played with the British English dub, and I think it was fine. Nothing amazing, but it does the job.

If you're curious about playing Ape Escape, and you don't have access to the original version, I think you can't go wrong with this one, in spite of the limitations.
