The Fallout franchise has yet to disappoint the fans but Fallout 4 will. Even when it is pending for an announcement by Bethesda, Fallout 4 is not expected to be spectacular.
This is evident if fans are to look at Fallout 3 and New Vegas. Both titles was developed with Elder Scrolls Oblivion game engine that is tweaked to offer better graphics and smoother renderings. If the pattern is to follow, then Fallout 4 will definitely be built on Skyrim’s game engine.
If so, then Fallout 4 won’t be looking to great, especially when running on the latest Xbox One and PS4. The idea for Bethesda to produce a game engine for Fallout 4 is unlikely to happen since that will only delay Fallout 4 for many more years.
Besides, having Fallout 4 running on Skyrim’s game engine will make it cheaper for Bethesda to produce the game. On top of that, Fallout 4 will be able to make an entry on the older gen consoles, thus, reaching out to more fans.
