>>41228768Gen 5 as well in all games. BW has a pretty even pace but gyms 7 and 8 are fairly far apart by the standards of the rest of the game. BW2 has a fairly large gap between gyms 6 and 7, and 7 to 8 is mostly Team Plasma stuff. However, unlike the other games where Gym 8 is basically the last thing you do before the endgame, BW2 has the rest of the Team Plasma stuff.
XY's last three gyms have a fairly large gap between them too. It's just the gym 3-6 section that is blitzed through.
An interesting thing I did in Blue recently was leave the last 4 gyms as late as possible. I had 4 badges and was around 3/4 of the way through the game. Then I did both Koga and Sabrina in the space of 15 minutes, and did the same with Blaine and Giovanni at the end.
I haven't played gen 8, but the gym pacing being wonky is nothing new, albeit it sounds worse than usual.
