Not even close. A friend and I are working on an iOS game (a tower defense style game). We are writing 0 code ourselves. We both have a history of iOS development, he is still actively involved and I've move away from it in recent years.

In about 2 weeks we have a functional game, 60 levels, 28 different types of enemies, a procedurally generated daily challenge mode, an infinity mode. Tower crafting and upgrades, an economy system in the game for pay for the upgrades.

This likely would have taken us months to get to the point that we are at, it was playable on Day 2.
