While I love the idea of having a friend explore and experience the vast lands of Skyrim by my side, there are just too many negatives for me to ever believe they'd attempt making Skyrim or any other Elder Scrolls games multiplayer in the future. These are a few reasons why I wouldn't want multiplayer (given that some of these things would be possible in multiplayer):
- This might seem selfish, but I do not want to share spoils with another player.
- It would be so frustrating if some immature (insert insulting name here) entered my game and started killing random NPCs that had quests for me later down the road
- The lag would be ungodly, I would think.
- I wouldn't want to play on lower graphics, considering Skyrim is so vast. Skyrim is only big for one player I believe.
- If you aren't far in your game, and another player was, you might have many things spoiled. (assuming that they wouldn't create certain quests you could only do in multiplayer mode)
- Every persons game has it's differences- the character's choice of factions for example. I don't know how these little differences between characters would be dealt with. For instance, if you join your friend's game and they're part of the thieves guild and you've never attempted joining...would you be able to gain access or even use their fences? It's the million little details and differences in every players game that would make creating multiplayer a huge challenge to make, and to make 'right'.
All in all, while this idea is initially exciting, I don't see it as being practical. I think they should continue on trying to make the best one player experience
