The final session of the day at Develop Mobile is a panel session addressing the key themes of the day.

Chris White from Glu Mobile started, who was very interested in GPS, and how you might use it to compete against players in your local area.

However, he wasn't as sure about using GPS to actually create content within games. "You want design to go into the levels to give you the experience that you expect," he said, responding to the earlier Nokia suggestion that map data could be used to automatically generate levels for games.

John Chasey from FinBlade was next up, giving his views on potential disruptive technologies. "With GPS, if we think QA is an issue with the number of devices, just think about what it'll be like when you start using GPS data..."

But he's interested in TV-Out as a technology, less so in Western Europe and the US, but more in developing nations where there's no significant install base of consoles or even PCs.

"TV-Out on a mobile phone connected to a TV, you do have effectively a console," he said. "Mobile can get there before consoles and become the platform of choice for gaming. There are issues around what device, and the need for alternative input methods. But TV-Out is a very interesting step forward in terms of where it could take the mobile phone in future."

He also pointed out that work needs to be done on the input mechanism for mobile games - "we've still got crappy keys".

Moderator Tim Harrison raised the idea of community, and gets panellist Josh Dalliwell from MobileYouth to talk about it.

"We tend to think of this as a personal device, so if you're consuming a piece of content or a game, it has to be a very personal experience," he said, before talking about his first experiences of gaming in arcades, which were social experiences.

He also talked about the lack of measurability. "I play this game and have a score, but how do I measure how good I am?" he said, referring to the fact that arcade games had high score tables.

So it's the community or social aspects, plus the measurability that he was getting at. And he illustrated that by referring to fantasy football, where people didn't care about being 650,000th  in the UK, but they really went for creating their own friend leagues, measuring themselves against their friends.

"Look at the success of casual games online, and poker, where there's just as much activity happening in the messaging and chat facilities, as on the poker tables," he says.

"I'm not talking about multiplayer gaming. We need to open it out to becoming a social gaming experience. Look at the success of Scrabulous on Facebook, where you choose who you can play with."

Will this ever happen in mobile games? Chris White said that new devices like N-Gage and iPhone could deliver this - "you know exactly what the user's getting, you can guarantee their experience a lot more, so when you do want to do these new more complicated things, it becomes easier to do it and easier to QA," he said.

White thinks Facebook is driving a lot of these ideas - the question is how to get that into mobile games.

Paul 'Monty' Munford from Player X (pictured) is up next, who (to put it politely) isn't impressed by TV-Out, multiplayer or community. "It's a shit business," he says. "I've been on these conferences for four or five years now. The problem isn't what's going to happen in two years time with GPS or whatever, but what's actually happening now."

He also expressed frustration about the lack of support for own-IP mobile games. "Nobody's prepared to take a risk on own-IP," he says. "We're lucky with Hollywood Hospital, because it's a franchise now."

He also talked about some of Player X's experience in the mobile video area, and how people get excited by viral videos like Harry The Hamster, but that mobile games is suffering - "the onerous activity you have to do just to get something published is insane".

Oh, and there will be some amazing big thing that will come through and change the mobile games industry, but "nobody knows what it is, and it will just be motherf***ing luck".

Dalliwell next took issue with the description of casual gamers, and people's surprise that women are playing mobile games. The fact that pensioners play bingo proves this, apparently.

What about Flash - something that's on more phones than you might expect, according to the M:Metrics presentation earlier. Is Flash the answer to mobile games, or could it ruin everyone's business?

FinBlade's Chasey says it's a cool technology, but it will increase fragmentation. "I can do a Flash game, but if it's a branded game, I'll still have to do the Java version, the BREW version and so on. Any publisher's going to want to hit all the channels, but ultimately it's just another platform."

Glu's White chimes in - "We're adding an even bigger between the CPU of the phone and what the user's getting. It might be fine for a simple brain training game, but if you're going to want to wow the user, you're still going to have to use Java and native platforms. Even finding good J2ME coders is very tough..."

Any more thoughts on the day? Chasey says pretty much every year at conferences, people have said 'next year, 3D is going to be huge', yet they're still not huge. "I like the fact that we often get things wrong in the mobile industry. Maybe one year 3D will get there!"

White is looking forward to seeing other handset makers catch up with the popularity and design of the iPhone. Meanwhile, Dalliwell says he still gets surprised by stuff - "it's amazing how the simplest things can excite people on mobile".

He whipped out his N95 at this point and waved it around, using the lightsaber app as an example.

Monty Munford finishes off, talking about going to a rammed pub where people were playing Wii Bowling. And he said he got more inspiration from seeing Batman in the local cinema this morning than from coming to a mobile conference.

"I wonder whether mobile exists any more in the games area..." he says. And on that note, it's off to the bar...
