Keep meaning to get into this mainly for tank/vehicle play is that side worth it?
Arma 3 Prairie Fire - So far during my brief play through, the vehicle combat is not good. The AI, even if you try to set coordinates to follow a road/track they will turn off and promptly get stuck in the Jungle. If you are battling in the open (still to test properly) I think it might be okay, its when there are lots of obstacles, the AI will go off and get stuck.
Still enjoying it though! There is an insane amount of tracer fire. Unlike Arma 3 where the enemy have armour so it takes 3-4 shots to kill, you can drop the enemy with one shot so you don't feel cheated. The weapons, sound, map and vehicles are awesome. You just have to have patience to work around the limitations of the AI, for example, play as a Platoon Leader and order the men to move, then it plays fine. I am really enjoying.
To me its a like playing toy soldiers and setting up silly missions. Tonight's plan is to try to emulate the gunboat scene in Apocalypse Now and then it will be onto rebuilding scenes from Rambo 2.
