1) WizKids owns the Shadowrun tabletop game, as well as BattleTech and MechWarrior.
2) Microsoft owns all video game rights to SR, BT and MW. FASA Studios was part of MS.
3) Catalyst Game Labs currently licenses SR and BT from WizKids.
So it's not convincing WizKids to license for video games, it's convincing Microsoft.
