What in particular do you think is so stupid about them? We buy PS games for 60 bucks, so why wouldn't you buy a new game for your phone for say three bucks?
when you put it like that

I think my argument is against mobiles in general -
If you want to make a phone call, then you use a landline (its much cheaper, but a tiny bit less convenient)
If you want to play games, then you go home and play on your xbox/pc/ps2/gc... (its no cheaper, but the quality of the experience is infinitly superior)
If you want to go online, then you use your computer (its massively cheaper, much faster, and the quality and flexibility of the content is far superior)
and if you want to compose ring tones... then you go and f***ing burn in hell you little annoying t***

basically, mobile phones do nothing new, they are simply 10 year old technology in a portable convenient format,
IMHO they have not pushed forward any technological boundaries.
But back on the topic of mobile games.....
I can't see the attraction in playing 20year old arcade games running at 10-15fps on a crappy 1.5"x1.5" B&W screen

Maybe that argument is a little short sighted, in a years time they'll prolly be 30fps on a 2"x2" colour screen

The most troubling[/sad] fact, is that ppls dopamine fueled game addiction is now inducing the need for games even when theyre away from their computer/console.
Another worrying issue, is that while the large proportion of the adult populance has the self-control to limit their addiction to gaming, the child population (at which a large percentage of the games, and mobile markets are targetted) do
not have this level of self-control.
