Funny enough, I made a blog post on Gamastutra about the same thing. Which I don't think got approved.
But you know, having played Sixty Second Shooter, it's an okay game, but I honestly don't really think it deserves to be a huge hit. $2000 in 4 months doesn't seem too bad to me. It's a common as dirt twin stick shooter that was originally a browser game.
Games are getting to be like novels in the days of e-books. I've written 5 of them. Put the sales of them together and they wouldn't come close to $2000. Would it be nice if I could make a living writing novels? Sure, but the same can be said for millions of other people out there doing the same thing. For most, there doesn't seem to be much of a market, unless you get ridiculously lucky, like that 50 Shades of Grey thing.
And I hate to be mean to the Super Icon guy, because he's nice, but while I liked Life of Pixel for the most part, again, it's a sort of game that lots of people are making. If you follow Kickstarter, there are a lot of platformers that blow Life of Pixel away and people aren't getting much funding for them. Super Ubi Land for instance. Or Tom Hall's recent failed KS. Whispering Willows.
Anyway, getting PS Mobile world wide should happen, but I think it's covering the major countries in Europe except for France, I think. It won't boost sales that much.
And I just don't think getting quality software is possible for PS Mobile. By its very nature (running on a virtual machine), it's crippled in performance compared to full blown games on either Android or the Vita. I don't know what sort of voodoo Sony used to get Lemmings working on PS Mobile, but if you look at say, Gun Commando and compare it to the FPS offerings on Android, why would anyone with a choice pick PS Mobile?
