Mega Man 10 - Beat the game as Protoman, and doubled it as a buster only + no items playthrough. The boss rush level was certainly nasty, but I'm better at all of them now as a result. Wily Machine drove me up the wall until suddenly I just got in a groove against him and he became fairly easy. Final Wily isn't too impressive, although was better than usual.
Then decided to play Easy Mode since that unlocks some challenges. ... wow. This game's easy mode is amazing. First of all, everything does half damage, and well over half of pits are now covered by platforms. And there are more powerups everywhere, including two of those "fully restore all HP and WE" items from MM1 per level. But really, this sums up MM10 Easy Mode best.
<Elecman> Solar Man: projectile has a new "tiny" default size which can be upgraded to normal the way it used to be upgraded to large. He is slower, attacks about a third as often, never attacks twice per jump, and the projectile is like half speed.
<Mega_Mettaur> this isn't easy mode
<Mega_Mettaur> its Butchered mode
Metroid Fusion - 1% run! Storytime.
Samus: Well we know the beginning will be easy. Hardest part is avoiding getting an upgrade by mistake. Oops, fuck. *reset*
Arachnus: rar, you have half normal HP for me oh wait I still suck.
Large Core-X and Zazabi: Yeah us too.
Serris: RAR I AM COMPETENT. Memorise my pattern or eat 4HKO and die.
Samus: Well I've finally caught Serris down... oh fuck if I make any mistakes against his Core-X at the end I fall in the water and die.
Serris: Hahaha. Too bad there are no other competent bosses in the first half of the game!
Samus: Dum de dum, well, nothing else in this level is going to kill me, but I'll go save anyway since I'm paranoid.
Missile upgrade in pump control room: HAHAHA HAVE FUN JUMPING OVER ME.
Samus: Good thing I saved. *reset x2*
Adam: Go to PYR and get some Super Missiles so your damage with your puny missile supply will actually be enough to count. Oh, and get an unavoidable missile pack on the way there so this is a 1% run instead of a 0%.
Samus: Lame. Can't I get an energy tank instead?
Adam: No.
Security Robot: RAR.
Samus: Whatever, I've learned how to perfect you. Good thing too, you probably 3HKO me.
Security Robot: I'll be back to make your life miserable lategame! Just you wait!
Samus: Now on to NOC... wait, blue X 2HKO me? Fuck. Need Varia Suit. Hey, bitch, give that back!
Big-X: Hey I'm less incompetent than usual because getting hit by me actually matters.
Samus: Wow, never noticed you only did 20 damage before.
Big-X: Shut up. Here, have my upgrade and I'll go back to pretending I don't exist.
Blue X's: Sweet, let's chase after Samus and near fullheal her repeatedly!
Samus: Thanks dudes.
Adam: Someone set up us the bomb.
Samus: Oh shit those purple snakey guys in walls 2HKO me now, and there's no way to recover or save while shutting down the boiler room.
Wide Core-X: I still suck. But you'll face me twice because the randoms on the way back from killing me are still deadly!
Samus: Yay, my beam doesn't completely suck now. This may be handy for when I actually need to start using it in boss fights that aren't Big-X.
Adam: Here, do a bunch of stuff that doesn't involve fighting bosses.
Samus: Snore.
Adam: Okay, okay, let's get serious. Go fight some Space Pirates who need 3 missiles to die and 2HKO you. Oh, and there will be no save point between fighting a bunch of them and the SOUS.
Samus: Spiders of unusual size? I don't think they exist.
Yakuza: LOL OHKO. *repeat x5 or so*
Samus: Yay finally learned how to not die to the first form!
Yakuza: Kay I'll go all unpredictable and still manage to 3HKO you. And of course you have to fight all the space pirates and my first form to even see this! *another bunch of resets*
Samus: DIE YOU STUPID FIEND. Okay, at least I won't have to worry about another boss OHKOing me until-
SA-X: LOL OHKO
Samus: Oh right forgot about you. *freezes and runs away*
Nettori: Haha you actually have to learn how to dodge my spores in form 1 now! Bet you weren't expecting THAT! Fortunately my second form is still bad. But it takes ages since you have to use your beam, and if you screw up the Plasma Core-X fight which is easy enough but potentially deadly you'll be doing alll of this over again!
Samus: *twitch* Well, at least now my beam does real damage. And hopefully there won't be another boss who forces me into using it.
Nightmare: You raaaannnng?
To be continued. I was worried at first but this run has settled in to being suitably hard. It's good practice for the bosses too, although some of it isn't too useful in normal runs... for instance, I now know how to fight Nightmare's gravity form without taking damage (not 100% reliable at it yet, 'swhy I haven't won the whole fight) but in a normal play it's easiest just to camp under him, take the odd hit, and blast away.
