Graphics... well I don't know... I don't like the graphics of POS, but I think Fallout 2 graphics were good... and they are still good... Fallout wouldn't be Fallout without them...
If there will be Fallout 3 the best would be, that the graphics remain the same... I don't want another 3D sh*t... why do today's people think that 3D is the _only_ future... Look at DirectX in DX8 and DX9 2D was wiped out almost completely... Fortunately I still have a copy of DX7 SDK for 2D developements...
A game isn't good because it's in 3D... and it isn't bad, because it's in 2D, but today's people think so... the question: WHY?
