You could always emulate(PSX, GBA, DS, SNES, maybe even PSP), and the touch controls are decent for turn based games, and some easy action games, like Kirby, but for more action-focused games, you could buy a controller, kinda like pic related(as in the design, not the brand itself), since they can stretch and fit most phones.
For Android only games, there are plenty of time-wasters, but a decent "strategy" game, that I like is Plague Inc, if you played the flash game, Pandemic 2, it's like that but more more variety, and you can choose were to start.
