I played this game around when it came out as a kid at a family members house we were visiting while sick.
My only memory was beating it and about an afternoon, that it’s story was completely nonsensical, and that it was basically just a mediocre call of duty clone but achieved my goal of killing an afternoon quite well.
Do you mean sapient? Because plants are also sentient; all sentience is is the ability to react to senses. Sapience on the other hand is the ability to have higher thought, like tool use, teaching, recognizing yourself in a mirror, etc… Finally there is the ability to feel pain which I do not think has a word. Plants from what we can tell cannot process pain, but can process negative stimuli.
