Grand Theft Auto V (GTA 5)
Now that annoys me as I like the online bit but being forced to have to play with others for things I want to do.... Na not cool. They should have NPC's in those for those who do not want to play with others.
You can never be ready for something like that.
If you start with a high server rack which costs a lot of money, then end up with way less than expected... then you lost money.
Although GTAV was a big expected title that people wanted, they never knew the exact sales figures before hand, and had a short window to get servers up and running.
They will fix it, but it will take a bit of time, its not like they have a warehouse full of server racks :P
