>>54711938>Rom hacksPointless difficulty spikes that mess up the game flow. I want the gym leaders and so on to be a challenge. Don't throw 3-5 trainers with 5 pokemon and megas at me while I'm walking from town to town. Just slows the game down while I'm trying to go find new pokemon and see what changed with the towns/cities.
>Fan MadeEdginess in stories, mainly. But a lot of fan made pokemon games also cannot balance a difficulty hack beyond putting a bunch of grass pokemon next to the water gym early on. This goes for romhacks as well. Most end up with forced gimmick fights and a PC box full of setters, sweepers, and other pokemon that you used once and left because they, even at a mid-game point, outlived their usefulness.
