Seems to me that the online issues may be regional in nature, or possibly related to the number of players in the lobby. I have zero problems ever since I followed the instructions
HERE, however that could be related to only ever having two players in the lobby.
...No update or DLC! pure silence from PD, and we are left with what seems to me like a half finished game. Please tell me this is not the future of online gaming.
In a sense you are right about it being unfinished. We are nowhere near the "end of the road", which is great. If you read
http://www.gran-turismo.com/us/products/gt6/ you'll see what it is that you should expect to have now, PLUS the plans for a lot of future enhancements.
To date they have given us what they promised, and are in the process of rolling out the other stuff.
If you were looking for a short-term experience with GT6, then you'll be disappointed. If you want a longer-term, engaging, evolving experience, stick around for the ride!
Personally, I'm hoping this IS the future of online gaming. It sure is the plan in ESO for example.
EDIT: "Is the game half full, or is the game half empty?"
