I've seen the trailer for BF3
It is mightily impressive, I must admit. It seems to incorporate some things about destructible environments that I have been waiting for, and the quality is simply gorgeous.
That said, BF2 had one major issue - it was very difficult to get a ranked private server. Possible, but difficult. Me and my pals spent three years running around dozens and dozens of user-made maps, upping our ranks on my personal ranked server, and it worked rather well.
With Battlefield 2142, that became impossible. I do not think that there is any way to get a private ranked server for BF2142, and that is really a shame because there are way too many idiots in the world to have a public 64-slot server work well, and I dont have 63 friends with the same gaming interests as I.
So it seems to me that, given that the publisher is EA, which has a proven history of being positively anal about DRM and user restrictions, I fear that BF3, though promising from a technical standpoint, will suffer from the same lame, useless restrictions that will make basic, user-supportive things impossible.
And that, for me, means that I most probably will not be playing it, because I find no fun to be had in playing with the general public that is full of idiots, losers and griefers. I prefer playing with my friends against bots - stupid as the bots are, they're still more fun to play than regular Internet dweebs.
So, if BF3 is going to refuse private ranked servers (and I see no reason to believe it won't) and, even worse, restrict private servers to piddling 16-player-size maps, then I'm not even buying the game.
Not until someone brings out a mod to blast those restrictions away.
Then we will see the usual treadmill of EA patch that changes something that breaks the mod, mod community gets together to find the flaw and patch it or find a workaround, and start over again.
Because EA can simply not accept that anyone else actually add welcome functionality to one of its products. They're not selling games so people can have fun, no. They're selling games because that is what sells.
