Returnal
I can't remember the last time I've had such mixed feelings about a game. For reference, I normally hate roguelike/soulsborne type games, and this is the first one I've enjoyed to any extent. The controls are tight and responsive, the bullet hell combat is exciting, the atmosphere is gripping (at first), the mysteries interesting, the procedurally-generated levels stave off boredom in repeated runs, and the gameplay loop compelling.
This game is also complete bulls***.
It tells you next to nothing about how things work, what will help you, and what will damage/kill you. It forces you to experiment, and punishes you for it by killing you off in new ways that nothing warned you about. It loves to throw lopsided risk/reward systems at you where the potential gains are usually drowned out by the risk or cost. But worst of all are the cheap-shots. Returnal's raison d'etre is to p*** you off and waste your time by throwing encounters at you that you don't stand a chance of surviving until you've learnt the attack patterns and behaviours of all the different enemies, and unless you're lucky enough to find the right combination of randomly-generated weapon and random upgrades to fit your play style or the particular mobs you encounter on any given run. It delights in throwing up to ten enemies at you at a time (including sub-bosses sometimes) and having them attack from all angles, so sometimes you die without ever seeing what blind-sided you. It has enemies that do an exploding kamikaze run at you after you've supposedly killed them. It has enemies that can kill you in one or two blows. Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.
Despite all of that, I loved this game for the first 15 hours or so. It could get frustrating, but I played by the rules. I got a genuine rush from finally defeating a boss, where in Dark Souls or Bloodborne I'd just be left with bitter anger at how long it took. But eventually the endless grinding repetition, the length of the runs, and above all the overpowered and cheap enemies in later biomes wore me down.
So I cheated.
Save scumming has only become possible in the last few weeks, thanks to a patch that now allows you to suspend and resume the game. It deletes the file when you load it, but if you have Playstation Plus you can upload the save to the cloud and then download it as many times as you like. This is the only way I managed to complete the game. If I hadn't it probably would have sat unfinished forever because tacking an hour or two of exploration onto each of the dozen attempts it took me to beat the third boss, or the 30-ish attempts it took me to beat biome five, would have killed my interest. Seriously, what were Housemarque thinking when they put enemies that can one-hit kill you into a game where every death in certain parts means repeating the last two hours?
Anyway, it's finished, and frankly it ends with a frustrating whimper. A lot of what kept me going was the sense of mystery, but the ending seems to contradict information found earlier in the game, and I'm not sure how much of it was meant to be taken literally. Considering that this game rarely dips below £60, I'd only recommend it to people with endless patience or no compunction about save scumming. Housemarque have intentionally tuned it so that only a fraction of players will ever finish it if they play by the rules.
EDIT: I looked up a guide, and it turns out the reason the ending was so underwhelming was because you have to complete the whole game a second time to get the true ending...
