I've been madly adding things to backloggery. I even started in on listing all the games within collections I have. That's a pain, but it'll be worth it when I start using the fortune cookie randomizer to pick games I haven't played yet. I'm going to use the wish list for all new games instead of preordering. Then when I am ready to buy something new, I'll randomize that too. Fun fun fun.
Not sure which one that would be. All the 1UP podcasts ended last year as far as I can see.
4 player co-op would be nuts and possible necessary late in the game. I'll see if two will be enough for some of those big bosses.
