Savage worlds is interesting.
Except when played on roll20, and their @#$%$@^@#$%@@11!!! not very random RNG. If its rolling 1s, you are about to see a lot of critical failures. When they should be 1 in 36.
And to kill off the main bad guy, instead of whittling down their HP, you need to whittle down their bennies.
I will look into Fantasy Flight Games
Look up the Genesys Dice app from Fantasy Flight Games in your Apple App Store or Google Play Store. Even if the rules don't appeal to you, it's a good dice app in general, and it's free now. They used to charge a nominal fee, I got it on Free Comic Book Day a few years ago when it was free as a promo, and now they just dropped charging for it altogether.
