How do buyers want textures set up on environment packages on the asset store?

AltoSlider

Hi all, long time lurker. I am interested in making an asset pack geared towards RTS style games for the asset store meant more for PC than mobile, and I was wondering how most buyers would prefer the textures to be done. Would they prefer an atlased texture or an individual texture for each building or prop? If I do a mobile version with significantly lower polycounts and a atlased texture should it be sold separately or bundled together?
