Didn't vote due to there being no options that fit me (yes I play them all the time, but it wasn't why I bought the phone
).
And it's surprised me how fun a lot of the cheap games actually are. I haven't bought any of the 'big' game tie-ins (Assassin's Creed, Sims, etc) and have mainly stuck to a few of the more quirky tower defense style ones and a few others.
I've since looked at the amount of time I've spent playing them, and they've stacked up quite well against mainstream games. For example let's say I dawdle through most mainstream games in 20 or so hours, and spend around AU$80 or so on it. Then I spend < AU$10 on a few simple casual games for the iPhone and have probably spent twice as much time easily.
(And that isn't even taking into account Puzzle Quest - which I bought -again- for the iPhone after already buying it for the DS, just because I love it so. Shame about the new one.)
Sure they're a battery sink, but when I'm sitting around half-watching TV or something at the end of the day, who cares? Play for a while, run down the battery, and then chuck it on charge overnight as usual.
(I tried playing games on my old phones that all ran through java - they were godawful. I don't know whose idea it was to put them on piddly little machines that could barely run the VM, let alone the games.)
