Did not know where to dump this so I will just do it here: there is a curator on Steam called Touch-friendly games that gives info whether games on Steam have touch support (he has checked ~320 games, most of these have touch support). Pretty handy alongside the touch category to find suitable games for Windows tablets.
ps: Sadly GOG is still unusable to find touch supported games. And ironically Windows Store seems to lack a filter to search for touch supported games.
