Well, not really. Obviously the process of actually making a real game is laboriously difficult and beset with more problems than you could ever presuppose (which is sort of the point), so difficult that any project of any size will find it hard to ever estimate how long their game will take to make. If we are talking man hours to actual end content making games is ludicrously difficult.
So maybe we can say finishing a game is hard, but actually making one? As in, getting out a tech demo/general proof of concept and letting it evolve? Now that, well that isn’t that hard. Getting the basic skeleton out of a game – if we are talking about indie games (and right now I’d like to) then we are probably looking at a clever variation on an old gaming trope. “Mario-but-with…” is the standard, and everyone knows how to make Mario. Actually getting your Mario+Variation to be a fun, challenging game (or a game that elicits an emotional response or -gasp! both) is trickier but experience has shown us its a manageable task. Hundreds of these things come out every year, all of varying quality, but with a little application any small team can release their own Mario-with-a-quirk game. Maybe we’ll never know the blood, sweat and tears that went into making all these little gems, but we can observe that right now the indie scene is damn good at producing them.
