lol no way. Birth by sleep is amazing.
Just a warning, try Kingdom Hearts before you buy it. Square forgot to pack quality in this one, not that any of them since the first have been past OK, but this one is just pitiful.
Every review I've read, watched, etc says it's, overall, pretty fucking amazing. 15-20 hours of gameplay PER character with a lot of replay value, deep character customization, ec.
