I have actually quite enjoyed seeing the in-game advertising - it does add a little "interest" to the maps, especially if they keep changing them - like your drive to work, anything that makes it a little more interesting can only be a good thing
Ordinarily I would commend a company coming up with another income stream to support with the costs of developing computer games (which is getting more and more expensive and is starting to approach Movie budgets!)
However, before I get the volin out for the poor software companies I must say that I totally agree with the idea that BF2142 is essentially a MOD! and therefore a reduction in price due to the advertising would have been nice
As long as the advertising does not affect my connection and cause lag I am quite relaxed about it
I don't even lose sleep about the "info gathering" - If I get ads for things I may be more interested in then so much the better - I am sure that there are loads of gadgets out there that I don't know I need yet
(but don't tell the wife!!!!)
