thatguy, you have a good point, but Drawn to Life wasn't as big as a success or as critically acclaimed pre-release as Scribblenauts was.
Also, Drawn to Life 2 (the Spongebob game wasn't made by 5th Cell, so it doesn't count) came out two years after the original, which, to me, isn't a "rush job." And the second one also improved on the original, though it didn't fix every problem.
So while Left 4 Dead 2 isn't an accurate comparison, Drawn to Life isn't a completely accurate one either.
To me, this is a case where the only thing we can do is wait and see if 5th Cell learned from their past mistakes and will truly improve Scribblenauts in the sequel.
