I like the controller. Much better having menus/maps on hands than going to menu and dig there. And then there's the asymmetric play (from common games seen in LEGO Marvel where other player can wander off and see his things on pad controller instead of splitscreen).
Most of the mileage change comes from different speeds used winter/summertime. I have absolutely the same mileage when I switch to studded tyres but still drive summertime limits (100km/h). When the wintertime speed limits (80km/h) come and I drive them, I get better mileage. Summetime range is ~900km/80l and wintertime is 1000km/80l on my volvo s80 (this is what computer says and I'm never actually close to emptying the tank, it usually only takes 55l at 700-800km mark)
Screw duty and selfless contributing, it'll only earn you ulcers. Do the fun and laziest thing and get integrated into community.
Fuck you, symbian & iphonetardos designers.
