- The new frontier part: iPhone development is brand new. It’s a totally different area (tech, financial, design, etc). It’s all new an uncharted.
- I’m one of the crazy ones that decided to jump in right at the beginning. I’ve been working on it full time for six months. Not the first by any means.
- Before that I spent over 10 years in the games industry Small companies, large companies Lots of games and platforms. This is my second startup.

- Sure, a lot of those are free, but still.
- As game developers we want to know what’s inside
- It is NOT your run of the mill cell phone
- Different than consoles. Apple doesn’t release exact specs.
- Actually this is quite frustrating. Less like a console and more like a PC. Apple needs to fix that!

- App Store!! Great access to customers (PC does not have a focal point for payment and ads, consoles have very restrictive approval process and far removed from final customer)

- Want to point out the great documentation and community
- Optionally, you can pay $99 to run your code on the actual hardware and put it up for sale on the App Store
- This is like the old 8-bit days without a barrier of entry. Anyone can grab it and start developing for it...

- The kind of games are different Controls, medium
- Medium is different. Played more frequently and not for as long
- Submitting your game for approval is nothing like with downloadable console games. Much simpler, lightweight. No preapproval. No portfolio.
- Can change your price at any time. Description, screenshots, etc. New versions need to go through Apple’s approval process.
- Daily reports of sales around the globe
- Right now fixed price per game New business models just announced (purchase in game items, subscriptions, etc)

- Lots of success stories! Rags to riches. Media loves these.
- If that’s the idea you have, let me burst your bubble right now
- The real deal: The App Store is flooded Except that now it’s 25,000!!
- Right now it’s a race to 99c. All about front page visibility, and top 100 are based on # sales. I don’t think that’s going to be that way in the future. Tide is starting to turn with developers foregoing the chance of getting in the top 100
- Remember Soul Calibur in the Dreamcast? Notice a difference? Lots of room for improvement.
- The big guys are coming to play. They’ll make a difference with many more resources
- Hard for very large teams to make money though. Easier for small teams.

- Rumours of a premium App Store with min prices Bigger companies, bigger games. Is it going to kill indies?
- The long tail will really help. Maybe rely on steady stream from several products
