Hello -
First off I posted by gamertag for PSN, XBL, and Steam. As you can see I use the same name for each of them. The next game I plan on playing is Dead Island on Steam. The issue now is that I have a broken headset and I need to buy a new one. I need advice on a good headset that I can use for both PC and PS3 (I have one for XBL). I appreciate the assistance and I'll run out soon to get one.
In terms of Warhammer Space Marine I thought it was a good game. About half way through it does start to get a bit repetitive, but overall it was a lot of fun. I haven't played it much online, but from what I did play it was fun as well. I'm not sure how the console versions are as I only played in on PC. With all the games coming out now, I'd wait until you can pick it up for around $30. You can already find it for this price now if you buy a steam code from a third party.
I saved my initiation question for last since I'm a bit nervous.
Since you are from the UK, my answer to favorite biscuit would be chocolate chip. In the US (where I'm from) I'd answer this with chicken biscuit from Chick fil a. Favorite beverage is pretty universal and I think you are referring to beer or ale. My favorite would be Fat Tire Amber Ale although it is a bit pricey here. Hopefully I did ok. 
I look forward to seeing you guys online!
