Hale is a turn based RPG with deep tactical combat and character customization. Included is a lengthy and varied campaign with many quests, items and monsters, visiting a variety of locales. The entire system is built to be moddable from the ground up.
Could not get it to build. Maybe you should include the libs required to compile game.
Maybe you can create 3D engine? 2D - is oldstyle, oldschool....
