I think it is a lot easier now than it was in the era of RBY & GSC. Back then, it's not like you could pull up Bulbapedia if you were stuck on a route or didn't know the type chart, etc. Through in walkthroughs, and Youtube, and it's much easier to get ahold of pertinent information. That power of the internet man! I think that's what Sydian was alluding to as well.
I thought B&W was really one of the easiest games in recent memory. One of the only games where I found myself over-leveled headed into Gym battles and the Pokemon League.
