If you ever played fallout 3 and skyrim you'd notice the striking similarity between the two games gameplays.. because bethesda made it..? well that doesn't stop them from making different games.. in conclusion: skyrim is fallout 4 in a different fantasy environment with dragons instead of nuclear bombs..
I'm not saying the game is bad so don't jump me already.. I enjoy fallout 3 and skyrim doesn't seem any bad.. I'm just saying that the gameplays are way too similar to each other like dante's inferno was with god of war..
Even if something's good.. stagnation is never to be taken over innovation.. it's better to go back to version 1 if you fail on version 2 than never attempt making a version 2..
