Arthur stealing Peter petrellis power wasn't a terrible plot line and giving him some of his power back made sense since sylar had a variation on the power too. If they had big kept their original levels sylar wouldn't have been a threat at all because he was stockpiling massive amounts of abilities that had no downside since he just understood how they worked and there wouldn't have been anyone to challenge that.

My hero a academia has since used an almost identical power system which definitely worked better but the idea of a weaker version being able to take on someone that can "steal" powers is still a decent story. I'd argue that all might (and later midorya) is the Peter petrelli in that plotline since they both had a form of power copying (gaining the abilities of past s) and lost them only to reclaim them through technology, it also forces the to get creative with what they have to match what they did before. For that reason I'd argue it's less of a retcon and more of a display of what the power (now in a villains hands) COULD do at it's full strength which became unavailable to the hero in question.

Was heroes on life by that point? Totally, but it doesn't change that it was a plot that had to happen unless you wanted a story about a guy who can do anything at any time with no pushback.

I know everyone wants to say thor can take sentry and on a good day maybe he can hold him off but let's not forget that sentry easily caught a bullet fired at norman Osbourne then ripped Aries in half. I'd argue that in of durability most of the marvel gods are roughly equal since they can all take a punch from some heavy hitters so I reckon he could bisect most of the of the Norse pantheon, maybe not Odin (or rune king Thor) at his prime.

Iirc hexcrete was an attempt to make an autonomous growing and self healing building material that worked perfectly fine except there was no way to stop it so it was abandoned and is just growing rampant.

I did actually know how to play caravan for a time. I looked up a guide and eventually managed to start winning games but I've forgotten over time. It's quite fun when you know how to play it.

I think we're going to find out that the canon ending is yes man. It's the only ending you can't lock yourself out of so regardless of your play style you can always achieve the yes man ending and it's probably what obsidian had in mind otherwise there would have been a no leader ending. I think new Vegas is going to look the way it did in the TV show because yes man makes himself "more assertive" and his robot logic probably isn't the best for the people of new Vegas, not evil just difficult to live under so people left after a while. There's no reason the courier would stay in Vegas once the job is done either so there's no worry about needing to create a courier character for the show that would appease every player and their choices.

I agree, it was already diminishing returns too. When you consider that the end showed Sam as an old man with adult grandchildren at the end it's canonically well into the future so there would be a massive problem with bringing the characters back from the dead. Are we supposed to believe that Sam died in what could reasonably be 2050 to 2060 spent some time in heaven then was brought back but the world is still the same as today? It just can't work.

Let it die, it was a popular show, it told its story and more and had a definitive ending.
