That right there, if executed well, could put a Vive in my hands.
Current plan is to allow for three forms of movement:
1. Real-world moving around, roomscale
2. Grid based movement option, with settings for how big the grid should be
3. Touchpad walking option, with settings for speed
You'd pick #2 or #3 as your movement option, then be able to move throughout the world. It'd be disabled when a monster entered your play area, so you'd have to kill them in combat.
Combat would be a combination of melee, ranged, and magic.
Melee would just be swinging swords, axes, clubs, torches, etc.
Ranged would be a bow and arrow, possibly some throwing items
Magic I'm still figuring out... could just be you pick a spell, press the trigger to cast it, done. Could also be you have to draw a shape to activate the spell, then can cast it. E.g., draw a circle in the air to cast a healing spell, draw an upside down triangle to shoot lightning from your hands, etc.
