The Fallout: Bethesda vs. Black Isle

XCGN has published an interesting editorial in which they compare Black Isle's Fallouts to Bethesda's take on the franchise.
'¢ Action Points - VATS:

Bethesda keep the turn-based combat which was so vital to the isometric Fallout games before, although this time the combat is far easier than in the previous titles.

'¢ Risky Exploration:

The traveling system is no longer risk free like in Bethesda's previous title Oblivion, with certain areas being no-go zones until you are far stronger. This is extremely similar to what Black Isle had in place and ensures that when exploring you don't venture into parts of town that are far too dangerous such as Washington D.C until you are strong enough.
