i really liked the fallout series, but new vegas was terrible!!! they added a lot of depth to it, but what they added wasn't much more than an expansions packs-worth of irrelavent bumf. i mean who really played new vegas and used the faction armour to fool other factions and sneak in and out of places? I found the story in new vegas pretty poor and was really disappointed that i ended up skipping half the story just by wandering around and exploring, poorly thought through, only really worth the hardcore mode and wild wasteland mode. i'd be very surprised if a new fallout game could hold as much relevent depth be it potions and alchemy, weapons and smithing, even character development. Skyrim is definitely closer to the Fable games, although i dont think i could play Fable after playing skyrim
big games like these often have glitches, skyrim on the ps3 is riddled with them and dramatic slowdown when theres more than 5 moving charcters, the xbox version is much smoother and seems to play within its limits, but skyrim is superior to fallout here too, there was more than a few points in fallout where i got stuck or would fall through solid surfaces and get stuck or my followers would get stuck and lost in fast travel.
love to be able to eat my words when the new fallout comes out, if they use the skyrim engine for it i very may well be
