Solasta: Crown of the Magister is an in-development turn-based tactical CRPG from Tactical Adventures based on the D&D Fifth Edition rules via the Open Gaming License. This is not the D&D IP and lore, but an implementation of the 5E game mechanics. And so far it’s really impressive.
From their Kickstarter page:
Created and written by lifelong fans of Pen & Paper RPGs, Solasta: Crown of the Magister is a Turn-Based Tactical cRPG heavily influenced by Tabletop RPGs.
An Epic Team Adventure – Create your very own party of adventurers in the classic tabletop RPG tradition with our Character Creation Tool. Breathe life into your heroes, and see their personalities reflected in their dialogue.
Discover a Mysterious & Dynamic World – Delve into long forgotten dungeons to unearth ancient artifacts, but be very aware of light and darkness. Many dangers hide in the dark, but a light can attract monsters.
Prepare to Think in Three Dimensions – The dungeons in Solasta are more than flat game-boards. Climb, jump, or fly around obstacles. Evade or surprise foes from above or below. Watch out, though – the monsters are also thinking vertically.
True to Tabletop – Solasta: Crown of the Magister brings back the thrill, tactics, and deep storytelling of tabletop games. As you play, you’ll feel yourself reaching for your dice and miniatures. Roll for initiative!
