Love seeing you perform no matter what, but really - don't you feel bored playing the same stuff for 30 years straight? money is money, sure, but don't you feel embarassed just a little bit to milk a cow long dead and buried? Don't you feel like doing something new?
One thing you got wrong. Emperor is still finding new places to play, new public to present their stuff live. That's much better than some mainstream bands (won't name any, but you know who i think about) who play the same festivals every year, the same places every year with the same playlist. That's boring.
