My brain is weird sometimes. I want to say "paradox mapping" when I mean "parallax mapping". This is really just because they both start with par and end with x, I believe.
My relationship with parallax mapping is a weird one, anyway. I have this strange love/hate thing with it. I love the way it opens up the world to new ideas and stuff, I mean--that's great! But I can't stand the rules that have to go around with it. In the back of my mind, there's always a small voice claiming "There has to be an easier way!" though I think that copy/pasting is about as easy as you can get with it.
And I'm always trying to cram too much into the map, too. I think about my own house, with stuff littering the counters and piling up in strange places around the edges of my living space, but in games that's usually too much for the eye to take in (I think so, in any case). Still, it's a great way to show the lives and personalities of the characters without even writing one line of dialogue!
