TOKYO: Bethesda was attempting to turn Fallout 4 into a massive MMORPG title but their move was blocked by Fallout’s original creator, Interplay Entertainment. The situation is really frustrating for Bethesda as they can’t do as they please with a gaming franchise that they have fully purchased.
Bethesda has decided that enough is enough hence leading to Fallout 4 to take a trip down the shredding machine.
The above is merely based on rumours and it is best taken with a pinch of salt. After all, there is no way for Bethesda to drop huge money making prospect in Fallout 4 that easily.
