I just completed the demo twice and I think there are some really promising ideas going for it. Saying it is a Final Fantasy Tactics clone is doing it a disservice.
There is terrain modification and limits on magic/skill uses. Combat focuses more on teamwork, buffs and debuffs. There doesn't seem to be class changes and each character has a specialized role with interesting passive abilities (IE. There is one character that gets a buff if he stands on a frozen tile.). The "Scales of Conviction" is an interesting idea, which flips the idea of the main character having agency and forces you to convince the majority of your party members to agree with your decision. You can also click on the X button at any time a person is speaking to see their portrait, what house their from and what their role is.
Even for a demo, I found the narrative and story in Triangle Strategy way better than the entirety of Octopath Traveler. And unlike in Octopath Traveler, you can move the camera and it doesn't have the jarring 2D Sprite on a 3D World look. It's not perfect though, moving the camera horizontally works wonders, but moving it vertically breaks some of the immersion.
There are a lot of things I didn't really like. There aren't any morally gray characters, they're either cartoonishly evil or virtuous knights. The one "Scales of Conviction" decision doesn't seem like a balanced choice. It is either to surrender the Prince to the villians or hold your ground and risk losing everything. Also it's not very hard to convince your party members to go with one decision over the other. The easiest way to get them on your side is by talking to every NPC and learning something that will unlock a secret conversation with them.
The game still has a lot of kinks to work out. There are framerate issues especially if there are a lot of things burning. The voice acting is off (like the House Falkins guy who is both monotonous and loud). The narrative is doled out in little chunks separated between 3-7 second loads. The combat is borderline sluggish and with the exception of magic, the main character and the Prince, no one else can really deal damage to foes. On my second playthrough, I played super aggressive, skipped through every cutscene and fast forwarded every action move and it still took me roughly 30 minutes to complete each scenario.
This game is on my radar but I'm hoping SquareEnix changes things after they send the survey out.
I'm curious what do you think about the demo?
