Skyrim

"For hours, possibly days without any interruption".

First: I install from disc and play that way

Second: I buy from steam and replay

Then: I buy from all console stores and replay on each respective console

THEN: I buy a new phone, jailbreak it and run Skyrim there

IM NOT DONE: I buy a new touchscreen fridge and re-buy, install there

FINALLY: I pay Bethesda to send out their Larping division to recreate Skyrim in my local park!
