Pre-release, I was interested in Anthem. I didn't end up playing it, because it was not well received. But, the concept is still of interest to me.
I never had any interest in Fallout 76. I'm just not into the Fallout series in general. With that said, it seems that this game still has a large player base, and receives content updates fairly often. So, it has that going for it.
So.... I guess I'll go with Anthem. I imagine I'd get a sense of what could have been with that game, rather than spending my whole life wondering about it.
