It's a short video thats really worth watching!
The speaker (an industry veteran) articulates what I have thought about on many occassions:
1. A "game idea" doesn't matter.
2. "Ideas" are cheap. Everybody has ideas.
3. Its easy to come up with ideas. The hard part is to implement it in such a way to make it enjoyable by players. Otherwise its just a day dream.
I also liked how he calls out the "idea guys" who just come up with concepts on paper but are completely clueless and inexperienced when it comes to making an actual game.
I found it funny because I actually know people like that IRL in the workplace who say "I'm more of a thinker" -- like as if everyone else around them are braindead zombies. What they actually mean to say is that "I just fart out ideas and I'd like for others to materialize my ideas XD".
