dude I'm a uber fan of the fallout series, the second I saw it available for pre order, I ordered it.
the pre order was also cheaper during the pre order special weekend, as was fallout 3, morrowind, and oblivion.
I enjoy saving money on games I know for a fact I'm gonna buy lol.
how you figure? it's the same as fallout 3, it's just new territory, quests, ppl... blah blah. it's not an expansion.
