I just got myself a tablet with Windows. While I do have a keyboard for it - I'm no peasant - I do wonder which games are naturally compatible with touch input. Features I also value with tablet-games are small file size and low system requirements.

I'd love to hear any suggestions. Here's my own thoughts:

Drawing-based games are perfect for touch-input, but this is a small genre. One I remember is CRAYON PHYSICS DELUXE.

I think the tablet ports will be likely candidates. But neither GoG nor MaGog mentions which platform their games originates from.

Adventure games are most likely touch-friendly, even though they are likely to require left-click.

It is likely that swipe and similar input can be implemented in certain games with Autohotkey. That program doesn't work well with DosBox, though.

I found this Mix:
Best Games to Play on Touchscreen Devices

Some games I have tried:

DON'T STARVE
I thought this would be perfect for touch-based input, but unfortunate enough, touch-input is broken in this game. You will need to double-tab to do a normal click.

UNHOLY HEIGHTS
Despite what I would have thought, the game does not play well with touch-input.

TRIPLE TOWN
Very touch-friendly, and a super small download.

ZOMBIE DIARIES
Most of the icons are large enough to be touch-friendly, but some functions requres you to perform a double click (by holding your finger down on the tablet). The game does not support swiping.

REDSHIRTS
Touch-friendly - but had both black border on top and bottom and free space at the sides. This is the kind of failed layout I expect from a VHS rip, not a modern game.

torchlight ?

almost everybody on here has this along with the witcher 1 and 2 ( doubt those are touch friendly)

I have heard that most of the females in both Witcher games are touch friendly.
