Seems like it doesn't take much work anymore to make a "good game", for indie titles at least.
It never did. The original Legend of Zelda was made by less that ten people, and it is still better than pretty much every multi-million AAA casualfest.
The Legend of Zelda was programmed on a weak-ass machine with severe limitations. The Gone Home "game" was cranked out in Unity, which does so much for you. I picked up that program and within one day created a small one-level FPS complete with rigid physics (I even threw in some cloth just for giggles), lighting, GUI, and a basic objective. Again, this was within a single day and that's including learning curve. It's so bloody easy to make a game these days. It's really just a matter of drag-and-drop and some simple scripting to glue it all together.
