I played Arkham Asylum at a mates place on his PC (With an Xbox controller on his big tv) and it was a blast, one of the better games I have played in recent memory, shortish, but so many good games are these days.
God of War collection looks fantastic, my brother in law has been salivating over it for weeks, but it hasnt got an AU release yet (that I know of). For those of you with a Wii, may I suggest getting the Metroid Prime trilogy (2 gamecube games with updated wiimote controls, as well as Metroid 3) Well worth your $70 or so from JB.
Rabbids go Home is a blast, but I am a big fan of he Rabbids series. Have to get the new Shaun White Snowboarding sometime soon, the first was too short, but fun none the less.
Just hanging out for Attack of the Saiyans on the DS, finished Pokemon Silver and the new Laytons games now.
Looking For: Wreckers Saga TPB Collection (with Requiem)
