Pikmin 3 is a beginners rts, possibly for those who've never heard of a mouse for control. Fun but annoyingly so. My Pikmin for a mouse, indeed.
As for mentioning the Somme, nothing wrong with that. mentioning such tragedy of war in passing jokes is not a problem, only if the oversensitive make it one. Yes, people died, but only through remembering such positively or negatively, can it be chalked up as something insane not to repeat. Its sign posted in history for you, to morn over whenever you feel the need.
When you are driving and run over a hedgehog, do you stop to your car and hold a wake and burial for it? No? Didn't think so. Try not to be such a white knight, Mr/Ms Genocidicles.
