How do smaller maps favor console players? I've never played on a computer before so I don't know how the experience differs. However, I do agree that the maps were too small.
I honestly have no idea however I can speculate in a very snobbish manner.
1. Maybe tighter maps lead to a greater percentage of firefights occurring at close quarters which may not emphasise precise aim, which is something that console shooters usually lack without automatic assistance.
2. Console online FPSs seem to go around with much smaller player counts, this could've originated from the lack of dedicated servers that typifies a lot of console games. A side-affect of smaller playercounts is smaller maps for obvious reasons.
3. Everything is smaller with console FPSs and those who play them; from tiny hardware (even the leviathan original PS3s and PS2s can't match a tower case for sheer bulkiness) to tiny amounts of buttons to tiny ****s. By having smaller maps the developers are avoiding the inflammation of console player's insecurities to do with size.
Discounting number three there are some plausible explanations for why smaller maps would cater to console players. Though really I'm not all that fussed about map size, it's more player counts that concern me. 12v12 pleaaaaassseee SD! As for "favouring" console players at least SD doesn't seem to be going the way of the guys who made shadowrun. I can't believe allowing PC and Console matches to overlap would count as a feature, especially when they had to compromise their game in a vain attempt to balance the two means of control in head to head situations.
Anyway Brink looks fine. I can handle 16 player servers, they're ok for TF2 if you have a good crowd playing and Brink looks like it's ticking all the boxes of a mult-platform release. I.e. not simply being designed for one and ported to the others.
