Yeah, seriously now.. What games?
Go read this, as right now we all pretty much think you're a quarter step ahead of Blasphemer in that you have a blue ball moving on scribbles.
Good job.
And I don't say this to discourage you, and I don't say it to be mean or rude, I say this to save everyone some time
Come back when you have a finished product. Come back when you have a game. Come back when there's a scoring system, a method of interacting with the world, a world to interact with. Come back when you have a game with a point of some sort, even if that point is simply "Drive in the world and run over zombies until you get sick of it and quit"
Because right now you're wasting everyone's time - ours and yours. I mean.. you're asking about Slogan suggestions. You've got a Breakout clone and a pointless blue dot on scribbles. I say pointless as you could indeed make a game revolving around a blue dot moving around a black and white world composed entirely of doodles, scribbles and a letter or something, and do something deep and meaningful with it - or at least marginally interesting - by mucking about with the text on the back.
But slogans? Now? Make a game first. You're arguing about whether or not you should put leather on the seats not just before you've built the cart, but before you've bought a horse. And... this is just an observation... any group of programmers, modders, whatever that I've seen that start discussing things like slogans before they have something they can call a finished product..... well, none of them are around anymore. Because they all fell through. Because they never made something they could call a finished product.
Again, I'm not trying to be discouraging here - I'm saying give us something to give a fuck about first.
