Fair! West coast games are generally more solid, but probably less because of setting alone and more since the developers weren't Bethesda lol. Although east coast factions badly need additions and refinement IMO. A Fallout game outside the US, or the coasts would be fascinating and I think there's a lot of interesting based on the mods like the one for the UK or Mexico, but as cool as that would be knowing Bethesda, they'll try to play it safe and stick to the east coast ;')

Isometric would be so so awesome :D I don't know if you know Newblood (I am a shill ashamedly, their games are the pride of my library) but they're actually developing an isometric game inspired by Fallout 1 and 2! I don't think it can ever be comparable to the games exactly, but since it's Newblood I'm pretty optimistic, and you might be interested if you're a fan of the old games too
