On the other hand, I'd much rather a client pitch a great idea that's technologically infeasible than just come up with something spur of the moment that they deem possible. If you start the conversation at, "This mechanic may not be possible, but the rest of the game is great," then you can discuss how to change the mechanic or maybe an engineer will have some brilliant insight about how to do the impossible. At the very least, you're starting with your best and working towards the technological compromise rather than starting with something that's already a compromise and may not reflect your best thinking.
Any pitch that starts with "this may not be possible" (even if that is inferred) is going to quickly get turned off by anybody who listens to pitches all the time.
This is why engineers generally don't make good sales people: the desire to tell the whole truth is usually too strong. The world of software is an incredibly dynamic space, so sales and marketing can use a little of that to their advantage. :)
It's impossible to know with 100% accuracy if a great idea will be possible or not. This is one of the reasons why I like the Lean Startup stuff so much, where you can be honest (with yourself, at least) about doing just enough to prove if something is possible/marketable/whatever before investing years and millions into it.
Or, as the author notes, sometimes you just realize the idea isn't going to work, isn't worth trying to retrofit into a sub-par result, and you're about to lose a rare opportunity to talk to the make-it-happen person. He came up with a better idea on the spot, and it worked.
Loved it, you could really feel the authors pain :)
I always sort of imagined this seat-of-the-pants type behaviour was unique to tiny indie shops & that you grew out of it once you became a 'real business', but I'm sure you'd kick yourself if you blew a big opportunity like that.
Anyway, can we extrapolate from this story and assume that most innovative game studios are geographically situated near vibrantly decorated restaurants?
Completely unrelated and a bit off topic, Matador restaurants were started by two friends of mine in '03 or '04 and are HUGE now. Just seeing the name-check pop up makes me proud of those guys and how far they've come from being a couple of bar managers in Queen Anne.
