Well you can add me to the list of people having a shit tonne of fun with this game. Despite all it's problems, the actual act of racing is a joy. If there was a competing driving game that had all the features in the world, working perfectly, but the actual driving was slightly less enjoyable, I'd still want to play DC every single time.
Have to air a couple of complaints though, hopefully they can get patched. Firstly the ghost situation - do these only appear on circuits? Was doing an A to B single event last night and never had a ghost to race against. Ghosts are a great teaching method of improving times. Let me dowmload a ghost of anyone online!
Secondly, give me split lap times as I'm racing! It's annoying as hell when one of your stars is 'finish in under x time'. You'll never get it on the first lap as you're starting from 0mph, but there's no way of knowing of you beat it on a subsequent lap unless you note the time you crossed the start line at and do a quick bit of arihtmetic to work out what total time you need to be under in order to beat the lap time.
