Aside from bus tickets and food, £40 on PSN vouchers so that I could get some Mass Effect 3 DLC (From Ashes, Omega, Leviathan & Citadel). I'm kinda bummed that I had to spend that much for the DLC when the game itself only cost around £11.
From Ashes was far too short for my liking but Javik is a very interesting character. Having said that, I feel he should have just been included in the core game. Omega was good fun but I kinda missed my squad throughout it. Starting Leviathan tomorrow.
This is also my first play-through of ME3 so I'd appreciate no-one spoiling anything, if you reply to this. I know full well the ending will suck ass but I'd like to think I've done well avoiding any more info than that.
