So how this is gonna work is i will post a question everyday and you can post your answers to the question. If you have any questions on this go to my profile and ask them. the first question: What is/was your best subject in school?
Telekinesis would be awesome. I'd form a ball of water or juice in the air in front of me and drink it like an astronaut. Hmmm... I wonder if I would be able to make myself fly, since that would technically break Newton's first law of motion.
Regeneration a la Wolverine. It's passive (don't need to actually control it), it's enormously practical in so many situations, and I don't necessarily draw too much unwanted attention. Perfect for me.
I have both and used to play Skyrim a lot, but after I completed everything that's fun to me with two characters I stopped playing it as often. So I'd say MW3. I can turn it on and play it for easily an hour by myself or more if I'm playing with people I know, but with Skyrim nowadays I turn it on and get bored after twenty minutes of gameplay because I can't find fun stuff to do anymore.
