It is just another way to screw you for extra cash, more hits, more balls bought. If they had any integrity at WGT then what you suggested TPN51 would have been implemented at the very start.
WGT had a promising game in the beginning but with ALL the problems that have NEVER been fixed for years now, it leaves me to believe that grabbing the clients cash is more important than any game satisfaction.
Imagine this senario, buy a WGT GT car, great stuff, all you need to do is change the wheels, the engine, the gearbox, the lights, the tyres, the petrol, the engine management system, Control will have to be reset every time, yes every time you attempt to start it up.
Don't moan about, just throw your cash at it and eventually your problems will just fade away into obscurity like all the other people who had the temerity to say so.
