Exhibit - Gunship (2000)
This sim is geared for quick action with the emphasis on tactical flying and fighting rather than button pushing. It's a blast!
The terrain was the most realistic of any sim in 2000. Fly up a road at 50 feet with the transparent cockpit on and prepare to be amazed.
Hitting enemy armour doesn't necessarily stop it dead - often it will keep rolling and smoking until a final explosion flings off the turret and leaves it literally rocking in it's tracks. Sometimes crew will bail out and engage you with shoulder launched missiles.
Between the trees, terrain, SAMs, AAA and enemy choppers I found staying alive damn difficult. Difficult but fun.
Just flying around in Gunship is fun and it doesn't require a monster machine.
An excellent 3rd part to the venerable Gunship series!
