I have not played Tortigar's hack, I only saw the video he uploaded to youtube long ago. I didn't know it's existence until I was already messing with the game on my own. Reading the list of changes, I think both hacks would play in a very different way.
As far as I can see, my hack wont be the same type of "hard" as Tortigar's, and it never was my intention to make it that way. What I wanted was to add variety and a little more freedom in battles, while improving the low difficulty of the original to a more interesting level without making it the main point of my hack.
Tortigar's hack seems to focus on what people already spammed during normal gameplay, Justice Shield, Delta Shield, Cutlass Wrath, boost stats through seeds, and make the difficulty around that...
On the other hand, my hack tries to give more importance to magic, so each character can fulfill different roles depending on the situation, and things like Justice Shield got a little nerf (costing more AP), for example.
Even then I don't think my hack goes that far into difficulty as Tortigar's could
So, If you come to my hack expecting the same thing as Tortigar's hack, I seriously think you'll be disappointed.
Another big difference that I'm thinking about is items, unless it's not stated in the features list. I've changed most of them, most important of all the healing items.
In the original game it was really easy to ignore healing magic in favor of spamming items, and if in Tortigar's hack they are the same as vanilla, probably it's easy to spam them too. In my hack healing items are nerfed, to the point that you need to learn magic to keep you up to shape, and you should learn magic with different characters to be prepared if something goes bad.
Also I made fish way more useful, and fishing is a great way to heal yourself out of battles.
Awesome. These changes sound really cool, and would affect the streamlined gameplay that Skies becomes after a while, in a positive way! (justice shield -> increm -> pirate's wrath etc.)
Would you consider making a Hard-mode for your hack, so that people who are looking for a more of an extreme challenge can get that from your version of the game?
