This engine is crying out for a World War 2 game...
Anyone else love to see a WW2 game based on FC3/4's engine/game mechanics? Open world exploration somewhere in Nazi occupied Europe, aiding the resistance, smashing up radar towers, clearing out Wehrmacht outposts, destroying convoys and generally being a pain in the ass for the local Gestapo commandant?
The only thing that wouldn't work from the last two Far Cry games are the wild animals and Wingsuit. But replace these with Tanks and I'd be a happy sapper.
