To summarize the other comments: Yes. -Very few games provide demos. -Steam allows refunds under certain conditions, but also reserves the right to ban accounts that abuse that system, and declines to define abuse. Therefore it's generally advisable to avoid using refunds to try games, and save them for when there is a issue. So there is definitely a gap where demos would serve well.
