I already knew I'd like the game, and I had 10 minutes with it at PAX, but I still wasn't completely sure what to expect from it as none of the storyline had been revealed and the starting Vault sequences weren't really revealed except for a few words and a screenshot or two.

Anyhow, it all seems to flow nicely together. There is however, one catch - this game is pretty hard, even on normal. Pretty much every expendable resource is scarce, although not survival-horror scarce. I regularly run out of ammunition and stuff to heal myself. Compare to Oblivion, which always seemed happy to give me a potion or arrows. I got myself in over my head in a subway near the beginning, and let's' just say that fighting fire ants with a BB gun is not very effective. Crippling definitely affects your play, from aim with crippled arms, to movement with crippled legs, to vision with a crippled head. There's no way in hell you're going to hit anything with crippled arms and a sniper rifle.

There are some technical hitches with the PC version, especially with CrossFire and SLI setups. It hangs up occasionally and then you have to wait for it to smooth back out. There's also the fact that the radio stations, while interesting, seem to have a pretty limited selection considering how long you'll be playing the game.

I didn't have any issues with SLI at all for the 3 hours I played last night... Only graphical errors I had where from Windows Live, whenever it would pop on saying someone had logged in or anything of the like and I was in conversation some of the shadders would go a little wonky until the little message disappeared.

Ammo scarcity sounds like the first two. It's wise to invest in melee skills to help you kill weaker foes so that you save ammo for raiders and super mutants.
