I said use what you need, not what you can. There is a world of difference between those statements.
I guess I was learning on limited resources too, which probably explains my attitude. I still think wasting space and energy is a bad idea
Even mobile games are clocking in at 1gb in some cases.
I doubt a producer, publisher or carrier would tolerate that size of binary - 180MB is pushing it in my experience and usually leads to office arguments.
Mobile dev is exactly the reason I have problems with the "Use everything you can!" attitude.
What do you have to doubt? Go take a look around. A gig is a normal, expected size for a lot of the better mobile games I have. The GTA games clock in that big. FF3 is a few hundered megs. Several games, like TDKR are 1.8 gigs. Wild Blood, gameloft's new UDK game is 720m.
Several of these games even offer HUGE downloads of high resolution asset packs if your high end phone or tablet supports it.
Even 3DS carts are 8GB, which is overkill, but there is no reason why they can't come in at 16, or 32 gb soon.
We are over the storage space hump in games.
