It seems like false advertising to me. Imagine a first timer logging and seeing that picture and thinking "WOW! This game looks great!" and then getting into the arena and seeing the low quality clouds and lack of vapor trails. I, personally, would be pretty disappointed.
Yeah, you'd be disppointed perhaps, but you wouldn't be out 50 bucks. The game's free for a two week
period, that's all the time in the world to see what you want to see.
Any other game, you spend the 50 bucks up front and if you discover it's not what you
thought it to be, well, you're out the 50 bucks.
