TotalBiscuit seems to share my opinion that it would be really fun to have a friend at my side instead of relying on Lydia.
I also totally saw this bile coming because it seems people hate multiplayer on principle which is stupid as hell. Multiplayer is NOT AUTOMATICALLY BAD. Mass Effect 3 is an example of a game where it's bizarre to have a multiplayer and I would never suggest it for 1 or 2. HOWEVER
Skyrim is a game with wooden characters, simple AI, and a mediocre story. The world itself is fairly standard fantasy stuff. In terms of immersion or storytelling, there's really nothing that makes it stand out. What's fun is the EXPLORATION. Running around the world, finding random encounters, messing around, experimenting, and just doing stupid things. That's what makes the game fun and those are all activities that are generally more fun with a party. Saints Row 3 is the same way, which is why I keep bringing it up, and people praise it for it's co-op. There's a reason Dungeons and Dragons always is played with a party. Skyrim can benefit in the same way WITHOUT SACRIFICING ANYTHING.
