The console generation already ended. What we have now are cheaper PC's, and mobile devices. It's just about branding the hardware at this point, and people will always want a cheaper alternative.
It's nice to have a bit of color next to your name but it really doesn't matter that much. If you can beat everyone senseless, people will know who you are. That's all that really matters.
mmm.... depends on who you fight, really. Beating higher ranks gives more points, and losing to lower ranks loses more.
Which means losing to anyone when you're high rank really sucks, but it's w/e.
Then that only leaves two possibilities. Bills got sticky and you gave too much (which sucks), or somebody stole it from the register. Either way, they will definitely look at you for not keeping it locked up.
At my old retail job it logged password entry when registers got opened. They didn't...
That's why you count down the register beforehand. And after that its your responsibility to watch it. Harsh life lesson in retail. But if you think it was a co-worker, narrow down a list of suspects and take note.
