Not bad, wish they'd mix it up a little more though

been waiting for these

Double minigame dates are quite annoying

mite acually have to train slayer

i might do this

Mostly looking forward to the free clue scrolls, but eh, might not even be on for those dates

Not bad, similar to last year.

I hope they do the advent calendar again though - I love free stuff.
