Reasons I think i should play:
I didn't finish the main story
I like fallout
There have been patches since I last played
I have nothing else to play
Reasons not to play:
bugs (but the ones i had were fixed)
many elements of the game I didn't like, restrictions on where you can explore, ridiculous terrain features, emptiness of the strip, inability to jump off the hoover dam
The main reason is Time Compression I have a Apr 20th deadline to finish it so I can play Portal 2.
