That went through my head, but I didn't want to confuse matters any further by throwing it in there. But yes, a full-price Wii game is $50. As for the handhelds, I consider $30 to be a full-price game on the DS (even though Square-Enix routinely charges more than that and GameStop charges $35 for some Nintendo releases). For the PSP, I guess it's $40 since that's what the AAA Sony franchises come out at.
I was just using $60 as an example for the 360 and the PS3.
I think that's an interesting, perhaps un-intentional point, though. Like I said in an earlier posts, developers know damn well they can't and won't charge a lot of money (i.e. 50 or 60) for a game that's clearly behind on technology and lower in development costs. You could say that it's in direct proportion to the generation the game might be classified as. Full on retail seventh-gen games are $60, last gen is $50, stuff like arcade ports are $5 whereas super awesome arcadey games are $10-15. It'd be hard, for example, to charge $60 for a port of Defender, because shit, man, that games like 20-something years old. At the same time, who in their right mind would charge $10 for Bioshock?
Mrs. Shipwreck's point still stands, though, if you had fun, then you've got no reason to complain about it's cost.
