Our entire business model is built around supporting individual developers and small teams, and while we've more recently started to learn to support bigger customers, it not how we think about our product and company and we've kept building and licensing great tech that we then release to everyone using Unity – the same for all, from the littlest indie shop to EA.
PS. I'm glad that you liked Boo, it's a cool language whose designer works for us doing many Mono and compiler-related projects.
PPS. Apart from being kind of enthusiastic about Unity and the business we're in I'm usually not told that I'm obnoxious, but I can live with it if I have to. In any case feel free to get in touch on twitter (davidhelgason) or by email at david at unity3d.com. Also would love to hear more about your bad experiences in Asia, these are new teams and maybe someone didn't get the memo about democratization yet.
[Edit: I received an email from Nicholas. I'll follow up with him]
Unity is a fine product as well. We have a number of Unity developers building their game back-ends on Moai Cloud, and we are working to build more features for them.
I'm currently using Unity. Their core product is decent but their team (at least the CEO and the sales guys, I haven't interacted with any tech guys) are obnoxious. I met with their sales rep in Asia (where I'm based) and he told me in no uncertain terms that they don't care about small teams. And that they were horrible at communicating because they don't see themselves as having any real competition. I think it's the fist time I've been heavily invested in a technology and at the same time wanted to see it become obsolete.
One of the best parts of Moai is Lua. I had started with Unity working in C# (seemed like it would be less performance bound) but didn't really like the toolkit until I switched over to the relatively obscure Boo (it has a Python-like syntax). Even with the almost total lack of documentation it's just way more productive than the other language choices. Switching to really terse scripting language has had a big impact on productivity for me.
