And it just kept going and going like that. Every new team had a strongman who was more powerful than Thor, the Thing or Subby, and then you got more and more cosmic beings like the Beyonder, Kubik, the Fulcrum, then a juiced-up Franklin Richards, the Sentry and who knows who else since I stopped following closely. Galactus became barely a B-grade baddie by that time, and that was a bitter pill to swallow.
p.s. As if two-thousand foot tall space gods weren't enough, don't forget that Exitar the Exterminator was himself ten celestials high!!
