Name better recent rts than Starcraft II.
Oh I forgot... You cant.
Better than Starcraft 2? Hmm... Starcraft 1!
If you have 3 different types of shit on the table and you have to choose one to eat it, you suddently think that the shit is good?

Sorry for my choice of words.
Let's face it Sc2 is Sc1 with pretty 3d graphics which are now a little less darker and a little more towards fantasy.
Sc2 is a pack of a multiplayer game, a singleplayer game and a level editor.
The level editor is good, it's just might be too complex but at the end of the day it's good.
The single player... with the exceptions of the missions and how everything flows within a mission... everything else is at it's worst (story, voice acting, how missions are structured, the full revamp from dark sci-fi to fantasy/sci-fi).
The multiplayer is good.... but it's not great as a game, because it has no new concepts. It's just the old concepts updated but not necessarily for better, but for different. The biggest change they brought in gameplay, was the Warp-In and the Queen.
Now as a pack which is like this, I would never pay the full price. I don't care about the voice of Tricia Helfer (who was brought in to appeal to the Galactica fans and for more public image) the voice acting of the old Kerrigan was much more better, I don't care about jumping debris, I don't care about 5 different death types. Those things don't show quality, they just show a lot of work. I would rather would not have 5 forms of death, but have a great story, would rather not have Tricia Helfer payed and have the old Kerrigan (for less money i might add). I would rather not have achivements but have a way different Terran race (currently I see no difference between SC:BW Terrand and SC2 Terran).
And the fact that SC2 is very popular, it has nothing to do with being a good game or not. It's very simple, people (regular people) want to invest into computers. They like computers, they like sitting at computers and so what do you think is great for them other then sitting on a computer and watching someone do something on a computer. Professional gaming (as a 'sport') will never reach the level of professional football (soccer for the US) in quality and entertainment. PC games might become at one point more popular than today's sports. But I think US Highschool teaches that popularity has nothing to do with serious quality.
Edit:
@Ramza, by Universe I ment franchise. When you are working with a fantasy franchise (like Warcraft or LotR) you are limited, you can't bring in the Predator or the Alien for example. Otherwise it becomes sci-fi/fantasy and that means revamping.
I also wasn't reffering to WoW, I was reffering to games in general. Not sure if the average age in WoW is 28, but anyway still, you can't say WoW is dedicated to mature people. I mean the content itself... trolls, orcs, elves, magic... that in no more mature than Harry Potter or Lord of the Rings (and btw, when Tolkien wrote The Hobbit and LOTR. he intended it to be for children). Maybe 14 is not the average age, but a child of 14 can fully understand WoW as a game.
And a little into off-topic now, the next patch in WoW is fail for me, because you will go through a series of three 5man heroics in order to attune yourself to the Deathwing raid. And basically in the first one you go into the future where Deathwing has won... and for me it's.. why would I ever want to go into the future? I mena... I think it's pretty clear that I want Deathwing dead... Deathwing caused the Cataclysm... that's good enough information for me to want him dead.. but okay we need to go into the future and defeat future Tyranda, Sylvanas, Jaina and Baine. Then in the second one I believe you visit the War of the Ancients... and you steal the Dragon Soul... and now wait a minute... I thought in the past two expansions we weren't allowed to temper with the past.... because otherwise in WotLK I would have opted to save Arthas. No Undead Arthas that means no Kel'thuzad revived that means Archimonde would still be alive but would not have entered this world, and Jaina would have a boyfriend. So all in all a much better trade right? But no.... now the laws of time travel change and you are allowed to change the past... that just feels for me that someone sat on the toilet, and while pooping came up with this ideea, and decided to serve it to me on a plattern in exchange for 15euro/month. No thx.
