I like to use pads as a substitute for a mouse. Games like peggle, zuma, and mini metro are great with the pads. I also like to use the pads with gyro to aim in first person games. Portal is a good game to ease into that.

I only really use them with the keyboard, desktop mode or any game that uses mouse emulation.

Age of empires II, I’ve cleared a few campaigns with it! Left pad as mouse region on bottom left icons, right pad as mouse.

right pad for mouse, left pad for hotkeys, all the way. Great for games that use the entire left half of the keyboard.
