Yup the levels are way low! And the gyms are just to simple! I like how complex the gyms are, and you gotta figure out how to get through them to get to the leader. The only gym I recall that was like in SS was the last one, in Viridian city.
I'm not bashing SS though, or saying Platinum is better. I love them both, I find it very hard to choose. I just like the gym system in Plat. better. And I'll definitely not be abandoning these games for the new one. I'm going to play the new ones, but I'm kinda nervous about how the 5th generation will be, so who knows.
