If you can, ask the shipped numbers for their predecessors....things like KZ2, LBP 1 and inFAMOUS 1 from the respective devs, so we can compare with VGC numbers.
LBP 2
Will it be difficult for users to create levels that are not platformer levels ?
Ask them whether we would get more premium level kits than LBP 1 which only had MGS and Pirates of the Caribbean premium levels.
KZ3
Ask them about multiplayer, co-op, story co-op, etc.
Ask them if the heavy feel of the controls are still there.
This one is very important. Tell them that you saw a video of an E3 demo, where the player died 2 times, but was revived by Rico. Is it impossible to fail if there is a buddy around you ?
inFAMOUS 2
Ask whether we would get more elemental powers other than ice ?
Ask them whether the boss characters such as Alden and Sasha return.
