Can a blender game which is made using GLSL, run on a computer which doesn’t have GLSL?

no but if you get your graphics manufacturers latest drivers i believe almost all have some glsl suport. if you are unsure if wha grapics your pc uses on windows you can go start>control pannel>device manager>display adapter and it’ll tell you what graphics hardware you are useing. just google the manufacturer driver downlads and the model of your graphics chip. then just download and instal.

Thanks rdo3…!!!

It can actually, but it’ll drop GLSL shading and resort to multi-texturing or the other mode and unless you’ve optimized for that viewing mode then it’ll look pretty bad.
