Makes sense. The basic AI in the later stages was clearly way too tough for a more casual player - i.e. my kids - so this makes sense.
As for the load times, from what I've read about the engine those sound hard to improve to me. I think it would take a fairly hefty patch changing the core engine or the developer managing to achieve a big leap in optimization - and given they seemed to have pushed optimization hard to reach the times that do exist that doesn't seem likely to me.
Pity, as the load times are a bit on the long side.
Try to be reasonable... its easier than you think...
