Unity recently published a series of blog posts discussing how leading engineers optimize for mobile devices. Popo's Mahjong doesn't target mobile devices, but the tips in the artices are applicable to all platforms. We've been making good use of these tips, especially from the UI article because card games are almost entirely UI. Other handy things include a visual look at the Unity PlayerLoop to know how MonoBehaviour methods are executed. Understanding and implementing these tricks here and there can boost game performance, responsiveness, and save battery, so we highly recommend taking a look!
