This topic is so tired and pointless. Are you guys in some sort of group and you take turns re-posting this every month?
iOS has Bioshock and XCOM for crying out loud. Android doesn't have those, but they do have Telltale games, GTA, FF, BALDUR'S GATE, etc.
You want to play serious games on mobile? You can do that. You want to moan on the internet about the lack of "quality" gaming on mobile when it's painfully obvious you don't know what you're talking about? You can do that, too, but the outcome isn't as nice.
And if you can't adjust your expectations for a different platform, that's on you. Even when we talk just lowly "mobile only" games, there's plenty of quality to keep a person occupied.
My phone has #ymbab, Bloons TD5, Crashlands, Deep Dungeon of Doom, Doombad, Elder Sign, Kingdom Rush (all 3), Hitman GO, Lara Croft GO, Plague Inc., Monument Valley, Organ Trail, Quell Memento, Ridiculous Fishing, and Threes to name about half.
I don't play them for hours on end, but I play them. They're plenty fun. They do exactly what they should, which is entertain me.
