For many of us, the line was hit or miss (mostly miss). It really suffered from a heavy use of diecast, which was essentially the gimmick of the entire line, and poor engineering. I really enjoyed the G1 Ultra Magnus (followed closely by WW Fallen and BM Cheetor). They're perhaps the best out of the entire line. And honestly, I thought Titanium Scourge was a nice Classics stand-in prior to the Generations release. Are there any Titanium collectors out there? I used to have a bunch before selling them all off a few years ago, but I'm thinking of re-buying a few.
