Amazon feedback said 16 GB. Customers complained that after having installed from DVD, the game nevertheless downloaded that after launch. Plus it is not just the P51.
Autoupdater - even worse. You want to fly, start the game - and it starts to download for the next 20 hours instead , blocking the rig. Ultimate fun killer.
No way to go for me, thanks, even more so since it will not be done just once, but several times, whenever World gets updated. This model is for people with reliable 16000 kbit/sec internet connections or more.
Which is not even 2% of users in germany, at least last time I checked.
I have 3000 kbit/sec - when the servers play ball. 2000-6000 is still the biggest norm group in Germany, although providers try to hide that fact in their advertising. Some promise 50000+ kbit via the powerlines. Do not expect to find many such users here.
