i only use 3 games: plague, words with friends and aerox.
i tend to use my phone for more constructive purposes, so i barely play the few games i felt worthy. the last thing i want is a phone full of pages and pages of cheesy games.
I got quite a few games, though I have also got rid of many. I love how judgmental some folks are, if you don't like games or prefer to play on (albeit largely superior) specialized devices ok. Some prefer to play on their mobile.
My games page starts with these 5 Rovio games too, the last 3 people that have asked to play on my phone have each said, and I quote "What the f tann how many Angry Birds do you need?!".
