Returnal - Well, I had the breakthrough I was looking for shortly after my last post, which I clearly was primed for given how much more I was enjoying it, and beat it a couple weeks back. I got past the Biome 2 boss on the first run at him, the Citidel took some getting used to, especially those fucking flying drones, but once I got the hang of it I was so over-prepared for the boss it was ridiculous (to the point I was pissed you basically start fresh in Biome 4 for narrative reasons; I still had two revive items =). The mid-game turn between 3 and 4 is awesome and made me think the best sci-fi movies of past couple of decades have actually been video games. Once I got used to Biome 4 I beat it, 5, and 6 consecutively, with the caveat that I stumbled into a common glitch that lets you bypass the final boss if you get revived at the Reconstructor (a machine that let's you resume a run from like a save room after dying)! That was weird, and I actually thought it was intentional at first, like game was giving me a divergent path, but nope, just a glitch.
I'm ambivalent about the squishy, vague ending though, which couldn't help but undermine the hard sci-fi elements, but at least it's open enough to interpretation I can have my preference. The secret ending didn't particularly help as I hoped it would, but it didn't hurt either. I wish they'd just played it straight instead of both going for a twisty gimmick but not even committing to it, to the point you can't even be sure which characters are are whom, let alone what happened to them. That was disappointing, but like I said, at least I can interpret it how I prefer instead of them outright confirming they fucked it up. =)
In the more nuts and bolts side, I'd say I had two memorably great runs in each half, not just where I beat the sections but created truly OP builds. The first in Act 1 was pretty straightforward: highly increased damage, upgraded melee, life, protection, multiple revive items, multiple healing items, a max damage weapon (Rot with like the doom power up) and like a 25% chance not to use consumables, so I was able to use my half a dozen or so healing items even more. I was basically fucking around tanking hits in the Nemesis fight and he still couldn't even force me to use a revive. The second was in Act II and was more unconventional but even stronger: I had the usual life increases, healing & revive items, upgraded melee plus a max proficiency weapon, but the real turning point was I had a malfunction removing item, then found an artifact that gave you a unique offensive power for every malfunction gained AND fixed, and in a room which also contained 4 malignant chests, one containing another malfunction fixer and child's watch! By the time I left that room I had like half a dozen rare and unique offensive upgrades that combined made Selene ridiculously OP. So yeah, probably never going to have a better run of RNG than that, but if you want to try to best recreate it save any malfunction cures you find in case you get that artifact, then go nuts. Anyway, great game, might be my game of the year, but we'll see....
