Has it ever occured to you guys how much development time was given for the iPhone games?
How many gigs the game was? How much the price was? You can't compare screens from a $50-60 dollar game to a $5-10 dollar game and accurately make a "Which is stronger" answer. That's like saying PS3 has sucky graphics because "Flower" can't beat Gears of War 2.
Personally, I think the iPhone 3gs can pull off better graphics against the Wii considering it's screen size. The psp can only do 333mhz ang I'm assuming a weaker GPU considering it's age and it can still pull off games like GOW, Tekken DR and GT.
Of course controls is a different matter alltogether.
