I haven't been very vocal in the past month or so because I have had a bit of a run-in with some illness, and then I had to get my wisdom teeth removed. So I apologize for the lack of updates.
On the upside I have been able to paper prototype the game I am working on, and once I have a document that fully explains the rules hopefully I will be able to share that with everyone.
In terms of prototyping for turn-based games I think its hard to compete with paper prototyping. Since so much of my game is influenced by tabletop war games I am able to break out a gaming mat, throw down some miniatures, and test out some of the mechanics. It sure beats coding up an entire game system only to have to restructure it when a major part of the system gets overhauled.
That isn't to say I haven't been coding - I most certainly have, but I found myself at a point where I was questioning how special abilities were going to interact with the initiative system. Instead of writing an extension to my initiative system, I just felt it was easier to print out cards, pull out miniatures, and dice it up.
I think probably all games can use a little bit of paper prototyping, while obviously some genres benefit from it more than others, I encourage you to try to take your designs, make them as small as possible, and then see if you can make a board or a card game to demonstrate one of your game's mechanics.
Thank you for reading! I hope to have some playtest documents for you all to try out next week!
