I guess my definition of a service-model game varies and wanders over to the developers simply continuing support for their game in order to draw in new sales, not discontinuing your ability to play that game. 'Cause yeah, that sucks. Obviously there's not much to do there for MMOs. They're expensive to run, and they've always been done on a service model. But on the other hand, it's not as apocalyptic as you guys are making it out to be - if they fuck up, if their idea of service is to say "no, we aren't making money on DLC, so you can't play," you're free to move on to a different game made by a different person, sometimes Re: sci-fi minecraft clone #487 even in the same genre and setting. That's their compulsion to help you - there's ridiculous amounts of competition for your attention, even coming from their own archives (why do you think they've started reselling older games, like it's some huge favor to the old fans?), and you're free to walk.
What game-as-service is supposed to be selling is the coordination and organization to support a game successfully over a longer period, and there are bound to be people that think that it's easy or that they can just lie. Drawing from personal experience, cleaning companies do it all the time. They go through workers like used tissue, even though it pisses off their clients, because they go through clients like used tissue, because every other cleaning company does the same to cut costs down to nothing-as-possible. It takes a special kind of sociopath to run a cleaning company.
That doesn't mean you can't do awesome things with a service-based model. I think - I even hope on some level - it'll have its upswing, it'll backlash, we might have another market crash, lots of people will lose their jobs as people realize it's ok to not buy a game every other week if what's being put out there is going to be taken away like a dog-toy. C'est la vie. If games really are art, it's subject to the same sort of commercialization that art receives, and the exact same sort of backlash against that commercialization that's occurred throughout history. Right now most people are doing the equivalent of contracted portraiture, sure, but that doesn't mean we don't have Dali's and van Gogh's coming.
You're a moron if you're getting a game development degree right now anyway - most of them are just re-branded and watered down business/marketing degrees with maybe a splash of indoctrination into whatever idea your video game culture professor has about video game culture.
Do some digging. It's exactly the same with the music/entertainment "industry" right now - the good shit is being done without any concern for megaconglomorate capitalism. Marketing is pure evil. Marketing has every aspiration you could ever have towards mind-control. If marketing had a death ray, it'd point it at an orphanage and tell you to buy. In a really scary, sort of deep gravelly hypno-voice. Ignore it, look at who's making a game including whoever's doing the advertising. Not just how famous they are or what big things they've done but whether or not they're enjoying themselves. Or just play and enjoy older games, it's not like they're going away.
