So I have done the survey as much as in my capacity.
I have not tried to do MMOs, or shooters as I don't play them to begin with.
Baldur's Gate looks not too bad, but eventually scrolling without a mouse is a nuisance.
Played some Heroes Chronicles. It actually responds well to touch input. Screen graphics are border line small. It is the only fantasy title I have tried that I might actually put on it later (used up a lot of my data space on wargames :) ).
I have essentially learned one big truth with Windows on a tablet. If the game was NOT designed for a tablet, it often will be inherently hard to see as the screen view will not be optimized for the size of the screen. If the game is not normally able to be scrolled in or out, then of course it won't be on the tablet as well and again, the view might be sufficiently small, as to reduce your thrill level.
When I compare the games I have on my Android using device, the games are made more likely to be able to contend with a reduced screen size. So just because you can put windows on a tablet, is no reason to be excited, if windows is really no perk.
I suspect 90% of the things I do on my Windows tablet, will be non game tasks that are not really at a disadvantage. For instance, I find I can type word documents on it reasonably well. It does though work best when I am sitting with the keyboard out and the mouse ready. The screen size though is not an issue.
To me, Windows on a tablet, is more about being able to carry an incredibly small computer on your person. But it only seems to be good for non gaming functions unless the games just coincidentally work out well.
So far it seems that Panzer Corps is the top dog for functions without need of added input devices.
Hearthstone is great as long as you have an internet connection of course.
I think the only area for me to explore left, and I am not sure I will do it immediately, is seeing how many of my Steam games like it. This is one area though, where Steam being installed without need of a hard copy present might be an advantage. I had no trouble installing Hearthstone direct from the internet.
