Care to take a guess? It has nothing to do with Final Fantasy or Pokémon (obviously). In fact, it has nothing to do with any of Sony’s flagship IPs. We’ll give you a hint: it’s fairly new to the PSN, which makes this even more amazing than it already is.

Still no idea? Alright here’s another clue: the plot is inextricably tied up with the notions of vengeance and rage. There are pigs, and there birds.

That’s right; not even the PSN is exempt from the madness that is Angry Birds.

Since going on sale in January this year, Rovio’s disgustingly popular Angry Birds has become the PSN’s most downloaded title – ever. Quite a few people questioned the merit in putting Angry Birds up for sale on the PSP and PlayStation 3, but it looks as if it was an excellent idea.

The fact that the game costs more via the PSN ($3.99) than it does on iPhone ($0.99) doesn’t seem to have made much difference to people’s decisions to buy the game or not. What this also means is that there is a healthy market for casual games on Sony’s network – a network that now boasts more than 75 million user accounts world wide.
