Judging from the colours of the plates (also the ones in the background), I'd say they're 15kg plates.
It's common that 5kg plates are white, 10kg plates are green, 15kg plates are yellow, 20kg plates are blue, and 25kg plates are red. The width of the plates doesn't change much from one step to the next, and, depending on the material they're made of, they can be pretty much the same size.
It's hard to judge the bounce, since that depends not only on weight, but material of plates and floor/platform.
I'm no expert either, but I've lifted weights regularly since 2012. This could easily be 50kg

The Hulk fucks his shit up in World War Hulk. It was fantastic. have a couple games of chess between flash and superman for ya

Yes.

Not really. Emotional impact might be personal, but story and characters can absolutely be judged on an objective basis. You've also conceded that basically every other part of a game can be measured objectively, so yes, of course a game can be judged on an objective level.

Are you just fucking with me?
If so, good job, because I legitimately had no clue.
If not, then you're a complete fucking idiot.
How do we judge anything if not on objective standards? How do we decide if something is good or not? Do you not understand the idea of a critic?
