>>44206470I can't speak for him, but I'm more forgiving of HGSS and other games like it because it also provides plenty of postgame content that's of at least a reasonable level of challenge. In this case, you've got E4 rematches, Gym Leader rematches, Red, and the Battle Frontier. The Gym Lesder battles themselves in Kanto were also fixed to some extent. And the superior map design of Gen 2, plus the lack of handholding, go a long way.
It's definitely true, though, that the campaign in Gen 2 is very much braindead easy outside of maybe two or three battles.
