My recommendations:
fix multipliers: Right now the rate you get them is extremely slow, and the timers for hobbies and such are so high that even high multipliers don't do much.
bug: Sometimes job achievements don't unlock unless you refresh the game, people who don't notice this may wind up resetting and losing out on bonus multiplier.
Hobbies too long: Same as everyone else is saying
please lock your PvP designer in a hole and never let him out for the rest of his life... I am sick to death tired of being told to win 4 PvP games for a daily quest and getting matched with nonstop level 70s while I"m only level 36, and have games that were sure wins completely overturned cause he just so happened to get 7 critical blocks in a row.
it's a nice time waster... Though one issue I have is the Newspaper costs escalate so much faster then everything else, to buy 10 newspaper stands at 298 it costs in the sextillions while my Oil derricks cost not even half a quint for 10 when I have 305 of those
