But normal game companies? Especially casual game companies? Do people really have that much faith that Candy Crush and the like is more than a generation's flash in the pan like Tetris, Pogs, or Tamagotchis?
No, but people have faith (quite often irrationally so) in their own ability to time the market, and be able to exit at the right time.
Activision and EA are movie studios. Zynga is a casino. Activision and EA want big hits and loyal fans. Zynga doesn't really care if you've played any of its previous games, or whether you play games at all; it just cares whether you'll play right now. (And maybe later, and later, and then more after that.)
(Of course, casinos also have their whales, as do Zynga-style games.)
This makes them a safer bet than companies like King or Zynga, which bet the farm on one particular quadrant of the overall gaming universe (casual games on mobile devices). If the world stopped playing games on their phone tomorrow, EA could survive that.
Whatever you may think about PES, FIFA was forced to evolve a lot to compete with it (everyone used to think PES was better). Progress has been more modest for Madden, which has had no competition for something like a decade.
It's such a tough business given that you need to invest in building a full game before you really know if it's going to be a hit. You could put out concept art, etc. but I'd argue that you can't really do "private betas" like what we do with SAAS just yet.
When the game got into a playable state he already got some followers. And the word started to spread. It was still a free Java applet at the time. Then people started to play it on Youtube and it exploded. And that's when he started charging 10 bucks for the game.
There are some old hotels (literally) out there that can still crank out cash and they're fine investments as long as you set your expectations appropriately.
I just the best talent will either start their own companies or join smaller companies where they can have more equity participation.
In a sense I see parallels with old AOL. They were still making money off the landline accounts sold to our parents, and did some copying here and there, but very little new greatness while they lived off the cash cow.
A better comparison might, perhaps ironically, be Yahoo. Not that Yahoo was ever as hated as Zynga, but after their usefulness as "the front page of the Internet" faded -- before the first dotcom boom went bust! -- Yahoo never really figured out what the hell to do with themselves, beyond continually insisting that they were an important media company. Somehow.
