I got a bunch of Reaper/Nolzur minis for player characters (fighting types plus one wizard, one healer) and Pawns pdf for Pathfinder, plus some custom made pawns I found for gnolls and orc-types.
I'm setting the game in a village with a dungeon or two nearby (downloaded the free dungeon from Heroic Maps) that's near the Savage Frontier in Forgotten Realms. I'll require some Deity selection to flesh out character creation, and I'll use my warmat for wilderness encounters, and the village set from Heroic Maps for village encounters. The game will be partly theater of the mind, but mostly done with minis and moving them from house to house even when out of combat to retain a feeling of gaming (downtime movement plus skill checks). I will set up the game so that it is like an MMO map, where you go to NPCs that stand around and conversate plus give quests or tasks if they have something they need done.
For system I will be using a conversion of AD&D/D&D 3/Pathfinder for the Hero System, which will allow me to kitchen sink all the classes and abilites into a cohesive whole without rolling with dozens of bonuses each time someone gets hit in combat. Also, I will probably use my own hack of the system to make combat even quicker. Also, a random activation mechanic (regular playing cards plus number of possible actions per character/NPC) will help the game feel more like a boardgame or something you might play on the computer with chaotic combat and tactics playing a part.
Hero systems more freeform character creation allows a wizard to wield a sword, rogues to wield plate, and mages to shoot blasts of fire out of their eyes if I want it to work out like that. It can do classical limited class options as well. I'm pretty stoked for this game, just because I finally got the ball rolling, and I get to playtest my own system hacks with it, which means I get more experience designing games and mechanisms.
The complete product will look different from what I'm listing here, but at least I have solid plans in place right now.
