Thats a really great idea, but making it a trend will make it go downhill..
The guys who make games by a trend usually just ruin everything, soon after this game style will become a trend you'll notice guys who make pokemons rape theis owners, these "trends" just ruin
all the unique and interesting factors in the game and make it a boring pile of doodies, before you're making the game, think if it's worth of even saying a word about making it a trend, the "trend" seekers have a rader for that.. you wont even notice it, and after a week there will be many games like this, but senseless, and dumb...
So i think you should be more careful and not even suggest such things, you don't know where these guys might pop out from.
It's an awesome concept, it'll be a shame to lose it.
