I never even bothered with it because I was just confused why there was no Battle Tower. I loved the Battle Tower in Sapphire because it was fun to test my teams against CPU opponents in a competitive environment. That one thing was what kept me coming back to it before I moved on from that game entirely. I would boot up my DS before I had much to play on it at the time and would just see how far I could make it in the Battle Tower. I AM ignorant, as I have no idea what the Trainer Tower entails, but the second I saw that it WASN'T the Battle Tower, I lost interest. Was I stupid for doing that? Maybe, but I was also still a kid, so I feel like if it was stupid logic, it makes sense. I have always been intrigued by it's existence since then, so when I get around to doing a full run of FR/LG again, I will make sure I check it out.
