Back when I first started working on Twice Upon a Hero, there were very few custom tiles available. My choices revolved around RTP, Mack and adapting some RMXP resources to the VX style (which can be harder than it sounds, mind you). At the time, my spriting was purely pixel and the painted style VX RTP uses seemed too intimidating.
Now that I feel comfortable with the painted style and, more importantly, now that I have some experience under my belt, I'm planning to recreate some of those early maps:
One of the big risks with doing graphical overhauls and remapping is that the developer goes into an endless circle of trying to keep all graphics up to date. As excited as I am about having updated maps, it will be a while before these maps are implemented. So far, I've only created the house you see above and it will stay that way until chapter 3 is released. Despite shiny new graphics, I don't think many players will want to play the same content over and over.
I'm also going to be looking at the gameplay a bit. One of the criticisms I've received is that there isn't a whole lot to explore or many places where the player can interact with the environment. As I'd like to have a well-rounded game, I am probably going to add extra rooms, areas and puzzles. Eventually, I'm also going to add more commentary from the party about various objects on the map. It's a good way to build the world, plus it's just interesting to hear odd tidbits about various things.
