I played Fallout 3 when it came out, and just got bored with it fairly quickly. It's got that Bethesda vibe where everything is great at first, but then you start to get further into the game and everything starts to seem copy+pasted to make the game artificially larger and longer. Is it like that at all? I see it mentioned as a great game all the time, but I also saw that about 3 when it came out.
I have more hours put into New Vegas then Fallout 3 and 4 put together. The writing is better like every one is saying If you have played fallout 1/2 it has a lot more of that really weird yet charming vibe those two games had. Also perhaps most importantly your choices actually matter, you don't get three different options to say yes and one to say ill come back later.
