$80 per game? Where are you shopping? Australia?
On topic: I find it helpful to compare value to that obtained from movies. The really good, AAA movies - the kind games are trying so desperately to be, things like The Dark Knight - cost about $8-$10 to go see in a theater. They last somewhere between 1.5 and 3 hours. That's about $3.50 or $4.00 per hour.
Expensive, yes?
Compare to games. If you play multiplayer - and that's a big if, as a sizeable portion of people don't! - you'll probably be able to get more hours out of the game than you put dollars into it, making it relatively cheap.
If not, though, you're paying $60 for a 5-hour game. That's $12 per hour. Three and a half times more money per entertainment-hour than the Dark Knight.
And that, friends, forms a quantifiable scale on which to measure the value of the games you play. Are they thrice as good as the Dark Knight? As The Lord of the Rings?
The market is built around multiplayer - around World of Warcraft, around Xbox Live, around Halo and Call of Duty and Killzone. All the publishers and producers chasing after that holy grail, trying to snare the biggest fish in the ocean - the multiplayer gamers. Sadly, that fish likes to bite at every hook that comes its way - it's just really good at letting go again after it's nibbled. So we get a long line of short campaigns tacked on to hefty multiplayer suites, all beckoning to that fish, all urging it to bite, to spend its $60 - and an equally long line of empty lobbies and dead servers as the fish moves on.
It's a self-destructive practice. You can't build a WoW killer, no matter how much you try, and you can't snare that multiplayer-gamer fish for good. He'll always go back to the hooks he likes most, or move on to the next hook that happens to catch his eye. And every dollar you pour into building more hooks only stifles the industry.
