"Which of the following mobile phone platforms do you primarily use?"
There's no "None" option.
Also I hope there's a post on the site later that has lots of graphs and statistics about the Giant Bomb community. I really need to know how many of you ate at a fast-food restaurant in the last month but didn't consume a soft-drink.
I'm sure I read that the DualShock 4 is compatible with the PS3 on a system level.
A quick Google search seems to confirm compatibility, but you need to have it plugged in via micro-USB and some buttons might not work (The PS Button, the touchpad, possibly the Options and Share buttons?).
Blitz didn't just port the House of the Dead: Overkill engine, they developed the middleware (BlitzTech) which was then licensed by the Sega team to create the game. That same engine powered every game developed by Blitz so they would be the obvious choice to work on a game that utilises that engine.
