Not sure about prices being cheaper because of VAT changes, it applies to all of the EU countries, so why make the Pound more expensive than Euro?
Its almost certainly because the EU prices were set when the rate was stronger, and since its hit a slump its become cheaper than USD, and the GBP price is just a rounded up number which reflected the price at the time, and again while the USD and Euro haven't done as well as the pound lately, those prices are made to look much cheaper because their currency has been made cheaper.
Also the nvidia poster is quite old, it possibly pre-dates the AMD Mustang deal. At least the AMD one, as unconvincing as it is, was done in-fiction to Star Citizen, rather than being a straight up billboard for sale to the highest bidders.
As long as CIG stick with their morals and only entertain offers which are in the best interest of the community which has funded the project, then i doubt we'll see anything of concern. As it stands, i think they realise they dont really have any grounds to start accommodating to any [extremely] early requests for advertising, funding is far from drying up, if anything its accelerating, and anything intrusive isnt going to be popular and when the community puts down $83m to support it, its impossible to argue slapping a load of Lucozade Sport & Norton Anti-virus banners in the game is productive or anything other than exploitative.
Im surprised that the gaming industry hasnt had the same sort of wave of advertising infiltrating it that other forms of media like TV, film & sport have. Tons of the US shows have been using their show to focus on features of latest cars, electronics, soft drinks etc, films have had everything with a label featured in them, and sports are no better. I enjoy watching NASCAR and the whole event is an advertising joke, from the Spongebob Squarepants 400 (seriously!
amusing pic), every car featuring a dozen sponsors, which every driver has to list on every interview ever before actually getting to the question, even down to segments of the race being sponsored, whether its logos in the corner of the screen or the commentator reading out the sponsors tag-line or films plot with the advert in a small window during the race or coming back from 3min of adverts - its 90% advertising, 10% turn left.
How its not become an unwanted, yet accepted, aspect of gaming is rather surprising. Games studios & publishers are no more ethical than broadcasters, film studios or sports franchises, and nor are the audiences any more vocal or likely to put up much of a fight beyond complaining and then pre-ordering anyway.
