can this easily run on the core BITD rules via something like foundry? i'm trying to find an alternative to CRASH//CART which, while awesome as hell, required just too much finagling to run via a VTT
Yes, there is roll20 support for this game! There also appear to be Foundry modules which exist for supporting players of Blades and its various Forged brethren, but I am personally not a user of that so I can't tell you how easily it runs.
