OT: Starcraft 2 Wings of Liberty

I'm quite a gamer and so, after the first Darkfall fever was gone, I've played other games that I haven't commented in here yet because of the blog title but I've decided to start doing it, under the Off-Topic tag.
Recently, I've finished Starcraft 2 first campaign and I've enjoyed a lot but not as much as I expected. First of all, I only play RTS for their campaigns; I enjoy RTS gameplay but it's not my favourite and multiplayer RTS are not for me. I like stories and Warcraft 3 campaing was great, so I was hoping for some more of it. Unfortunately, Wings of Liberty doesn't deliver. Maybe the campaign is too long for its own sake or maybe their saving their best moments for the Protoss and Zerg campaign but it's not as good as it could be. The lack of heroe presence in the battlefield might have something to do aswell because you could get into Arthas skin very easily but it's hard to enter Reynor's.
Despite all that, Wings of Liberty is a nice and polished game with a very nice "campaing navigator" in the Hyperion and full of different misions. Actually, it's probably my fault, you know hype is very bad.
So, what could Darkfall do to improve it's storytelling? MMORPG narrative is a hard concept but I think its basis should be: Players can influence the state of the world and the state of the world does influence the player's experience. Darkfall already does that but not a lot. Hopefully that will change with more events. We shall see.
