Fallout 3 or Valkyia Chronicles?

[flagship]

In about a year Bethesda with rerelease Fallout 3 + some expansion material in some deluxe or GOTY version so if it isn't a must have you might as well wait until then to buy it.

I'd buy Valkyria Chronilces, from what I've seen so far it's the one PS3 game that makes me regret not owning the system.
