An update on Mega Man: I've finished all 6 games now. Even though the gameplay improved marginally after the first few, each game was more excruciating to complete. The ending sections against Wiley and his predecessor seemed to get longer in each game.
For those not familiar with this collection, there is also a challenge mode, where you can play premade scenarios from the 6 games. Sometimes they are small sections of several levels tied together, other times they are boss fights, and sometimes they're a combination of both. There are 54 in total, although you have to beat a few of them to keep unlocking the next ones. One of the trophies in this game is to get Gold in 50 of the 54 challenges (the rank is based on how fast you beat it).
This is unquestionably, one of the worst and most difficult things I've ever come across. I think it took me 40 minutes to get gold in the first challenge, and the time required was under 3 minutes, so it wasn't a long challenge. Some of them are easier, but the only "easy" challenges I've found so far are the shortest ones that have a method where you can cheese a boss fight. The worst ones are the ones with several sections of a level tied together because each section has a unique strategy based on the weapons you have, which you would never guess how to complete on your own. The only good thing I can say is that you can view replays of the top 100 times on the leaderboard, although many of their strategies are too complex for the average person to execute, so I still have to look up a more achievable time.
I've done about 6 of the 50 challenges needed and it has taken a few hours to get this far. I will keep grinding it out and get them all done, but I think playing this game and Bloodborne at the same time was a bad idea because both games are so difficult that sometimes I don't want to play either. I've made it to the DLC in Bloodborne, so maybe I'll try to power through that so I can have a more realistic backup game when Mega Man frustrates me.
