Every now and again, I get the idea in my head to go through all the Lego games, from Star Wars all the way through to... erm whatever the last one was (they get less memorable as the years go by) - Ninjago or something like that. I still have to drag my PS3 out in order to play Lego LOTR.
And speaking of LOTR, I find myself revisting LOTRO every other year or so, starting a new character and then never getting much past Moria. I was doing it again when returning to COH took my fancy.
