A Warthog, the Portal Gun, One of My Saints Row 2 cribs (slightly modified), a pip-boy, A WH40K Space Marine Dreadnought (Black Templar), an unnamed (so far) space ship, (I can use the portal gun to supply food etc through portals), another form of teleportation device (preferrably something large and stable that can work from anywhere to anywhere), A Master short sword (Fable), one of those "can't sustain damage" suits from insert-game* (light, breathable, can change size and color) and last but not least that cake from the end of Portal, just to see what flavor it is.

Why would I need anything else

?
You could go sit down somewhere while
at the same time riding a rainbow into the moon eating cheese while on fire!!
I chose a lot, and I would take any of those. Because they are all awesome. Maybe not practical but practicality is for the weak/prepared.
