You can't fool a casual (gamer) thrice

What I mean is... why software houses are trying so hard on the average casual gamer? How long do they think it's gonna last?
If a person that just got close to videogames buys a really bad game, one of those games that swears "Fun for the whole family!", and then turns out to be boredom for the whole family and even the pets, maybe he will try again.
He could buy another bad game, but that's it. There's a company (whose initials are D.D.) who developed a complete series of bad games in a few months, each one similar to all the other ones (although being different genres). How many they think they can sell, after this bad service to the player?
I'm referring of course to Wii and DS situation, I'm sick tired of seeing a bunch of cash-ins every month. If they keep going like this, each casual and potential hardcore player will turn off in disgust from videogames.

You can trick a casual gamer into buying your game once. Maybe you can fool him twice. But you can't fool a casual THRICE.

(actually some get fooled more than ten times... but not all!)
