whether you know them or not i would suggest watching doctor who. Well the tenth doctor ones anyway (david tennant) as he was unreal as the doctor.
In case anyone's really worried, Googling is totally fine by me. Just got to put some limits on it so if I say 'yes' to Star Wars, we don't end up with 5 immediate identical posts each listing about 500 races from a list that's been googled up When I was refreshing my memory on Daleks I came across a quote saying 9 out of 10 British kids could correctly identify them (from a picture, I presume). There seems to be a lot of 'soft' sci fi and genre fiction that's mainstream in the UK but nerdy elsewhere - Who is probably the best example, Pratchett is another.
I'll admit to googling, but i do so only after i know i'm not gonna know the answer. I wont start off googling every alien ever created, then one by one mark them off by process of elimination till i get the answer.
Getting late here, but I'll suffer arseing around on the internet while having a glassbottle or two of wine to bring you ROUND 6 Stick to 5 questions or suggestions between my answers to you, please As always, all previous rounds' answers are void, and the things I'm thinking of may already have been suggested.
Eh, I'll take a quick stab with the martians from Destroy All Humans. Questions: Does the game have any sequels? If so, do the aliens also show up in those?
