So, believe it or not, I have still been working on the next sequel, and it's getting close to "demo-ready".
Over the last couple days I've been adding the market, where a player buys and sells cargo in various cities - the primary way of making money, other than completing storyline jobs.
The biggest thing that keeps slowing me down is iterating on the User Interface. I think a lot of amateur games consider it of secondary importance, "I'll fix it later" - but they never do, and in a game, the experience is everything. Cursed is a wonderful game, with great writing, but it's a horror to look at.
For a game like the one I'm developing, there's a lot of information to squeeze into not all that much space. How to present that information without causing "huge wall of text" issues is an interesting challenge, and one I keep iterating on. Lots of mouse-overs is one method - and unlike BrothelS.im, the mouseovers are aimed at providing mechanical information, rather than flavor tidbits.
Another method is consistent colors / layout, hinting at what things mean without needing to make them explicit. Stats are always ordered a certain way, so when you see an empty box with a couple of dim numbers, it's readily apparent what it means - fill that box with a character matching those numbers.
Anyway, I'm still not 100% happy with some of my solutions, but I think when you see it in action you'll see how much I've learned in the process and agree how much of an improvement it is over my previous games. :)
