I had never played any Mass Effect games before playing Outer Worlds. I loved the companion aspect of that game, but it was a pretty short, small game. So when I played Mass Effect, I was blown away. I don’t have the same complaints people had for Mass Effect 3, because my experience was with the legendary edition. Yeah, the 2000 Space Odyssey ending was weird but it didn’t ruin the whole trilogy. I’m now playing Andromeda and sadly not enjoying the companions as much. Hopefully that changes as I progress through the game.
I would say no. The earlier games are very very different types of games. If you played the earlier games, I think you’ll appreciate Kratos’ journey more but it’s not necessary, imo.
