I bought Angry Alex, and really tried to like it, but got bored and gave up. I ended up going through all the old Angry Birds scenarios dating back to the beginning, instead.
Angry Birds is relaxing. I spend my days writing code and prose, communicating and creating. Playing Angry Birds is not about creating (obviously) it's about destroying. It's a perfect game.
I'm sure that Rovio wants to grow, make more money, hire more people -- but maybe that wasn't meant to be. Maybe they should be happy with the success of Angry Birds, and try to do things to make their fans happy. No one would begrudge them some more money if they're helping make our downtime more relaxing.
Anyway, I seriously think that Angry Birds could be a platform, and that's what they're trying to create with these other products -- including the new Bad Piggies, out today, which I admit I don't even want to try, because the idea seems like another Angry Alex, but this time with an element of the Angry Birds franchise.
Instead, why not release the design tools they use to create Angry Birds scenarios, and open a store of their own. Let creativity rule. Even if the scenarios were just ripoffs of the ones done by Rovio designers, so what. Let's see what people come up with.
An idea -- give the pigs and birds recognizable faces. Of movie stars, baseball players, LeBron James, Carmelo Anthony. Or Republicans and Democrats! There could have been a special scenario around the death of Neil Armstrong that had him and Buzz as birds fighting off lunar pigs (whatever they might look like).
I think there's still room for a lot of creativity with Angry Birds. Stick with what works Rovio! :-)
