PC games come in DVD cases here, same as console games, sometimes with even more stuff (Earth 2160 came in a cardboard box with a motion sensor, much-thicker-than-usual-but-still-lacking-vital-information manual, folding disc case and a soundtrack CD). Of course some multi-CD games have those annoving three-on-a-pin DVD cases but as multiple CDs are being replaced with DVDs that problem is going away again. Oh, wait, in the US you don't get games on DVD yet, I've heard?
Console games rarely drop in price here. Usually it takes about a year for the first drop to 30€ (whereas PC games often have hit 10€ by then). Discounts never apply to games here (seen that once, the store was cleaning inventory because it was going out of business). Rarely you'll see a store do special price drops on games that don't sell (e.g. Karstadt is selling Shadow The Hedgehog, Animal Crossing, Metroid Prime 2 and a few other games noone bought for cheap right now) but since not selling usually has a reason that's rarely worth it.
If the license fees on console games really make a 20€ difference then I'll put some of the blame onto the console manufacturers as well. But I don't think licensing fees really are 20€ for any console.
Also why do console games take forever to get localized and usually just have the texts swapped out when PC games are released within days of their US release (for locally made games usually much earlier) and with full dubbing?
