*eh* the game hasn't been released ... and the demo is a mere beta.
It's a mp-only demo, so I don't know how good/bad the AI will be.
They definitely have to get rid of the connection-problems. I hope it's just a server-capacity-problem, because anything else and the game is in serious trouble with a mere month or so until release is expected.
Graphics are merely average, some might say below par for today's games.
Think of it as OFP with an attempt at modelling decent trees and some grass for cover and stuff that can be destroyed. It doesn't look like it needs the speed for the eye-candy, altough the playermodels look pretty good.
It uses a money-system with a personal & team-account for vehicles & weapons.
At the start of the game you can't afford more than a single rifle.
It does have iron sights ... but they're very very ugly sprites. There is a different sprite for every weapon.
Jumping is only useful for minor obstacles. Altough you can jump through a window with a nice animation to match.
Sprinting is limited by stamina ...
