and you can actually build useful stuff while "stacking bricks"....
useful in what way? adding more side quests? Why spend 70 hours building stuff to get the "end game" or "best in the game" armor/gun if all I can do is go around 1 shotting everything? No challenge or skill involved.
but hey this is my opinion. That's why I play multiplayer games. To do crap with other people not just myself and because end game changes with new content. Games like EVE and SC you can work hard and stack bricks to get useful things, then go out and get it blown up or blow stuff up with it after. In games like WoW and other MMO's you stack bricks to get that end game item you then use to kill a raid boss you couldn't kill without it. After all the grinding and building you can muster in the 189 days of play time you put into them there is always something new to do when you log in. By that I don't mean go looking for a tiny bobble head hidden in some obscure corner either. I mean a new group of players moving into your area, or expansions to continue leveling up and play new content.
Once your max lvl in a single player game everything stagnates out and nothing gets harder or changes and there is no one there to share it with but yourself. Yes you can up the difficulty or do hard mode and such, but that doesn't change the fact that there is nothing new to face beyond that. New content from their DLC crap they nickel and dime you with just adds more story. Play it once and now you know the story. No need to replay it again and again and again for 1000 hours. That is why I cannot play a single player game for much more than the main quest. I play a single player game for the story, not to wander aimlessly finding side quests that have nothing to do with what drew me in the game to begin with.
I am sure its a great game. I know at some point I will buy it and play it. But for me, I will never spend anywhere near as much time in it as some of you guys here. There is nothing wrong with that.
