I have a ludicrously modded Skyrim, and I like my mostly vanilla Fallout 4 as much as that, but probably more than vanilla Skyrim.
Once Fallout 4 is heavily modded... no contest.
(I had Fallout 3 modded... even had Moriarty’s bar in Megaton modded into a strip club complete with pole dancers)
I didn't get into modding until Skyrim came out. I had never even heard of them before that.
I've been playing video games since Pong, and the notion that I actually had the power to CHANGE the game myself just blew me away.
Thanks for the response. I'll probably get Fallout 4 pretty soon.
