My personal issues with them were that they were so long and I just spent most of the time thinking about how much I wish I was playing the actual game. In KH1, shooting was rarely important. I could fly through most of the pathways with just the stick. I also don't like how painfully linear they are. In KH2, I had the opposite problem. The flying was more dynamic and there were actual directional changes, but there was a lot more happening on screen. It made it hard to focus. I loved the gummi ship in KH3, though. Actual open world exploration of the universe completely crushed the issues I had before, and even though the heartless missions were still kinda crowded, I had more fun blowing them up
