I wasn't incredibly fond of the first GoW, it has the syndrome of "the introductory entry where the concept hasn't been fully realized yet by the creators". It's not a bad game by any stretch but it is dry in comparison to its much more ambitious sequel. The sequel is basically a much better version of the first game and it also introduces a bunch of new mechanics and tools that all flow incredibly well. The combat is more fluid and less repetitious than GoW1. The platforming while can be janky at some parts has seen a major improvement and is nowhere as migraine inducing.
Overall, fun game :) but lacks gay sex minigames with greek men.

I feel that HM1 had a more unique and subtle tone with its storytelling. 2 just goes really hard on the nihilism and the melancholy of the story that it desperately wants gameplay to reflect that (lol killed off screen by silly russian man).
HM2 can get monotonous, frustrating, and depressing, and it drags a lot in its pacing and combat but eh, I still had some fun, I just won't be in a hurry in coming back to it, unlike the first game.

imo DDLC does a pretty tasteless interpretation of depression and suicide. It relies on creepy-pasta tier shock value to get across its themes, and doesn't provide any nuanced exploration as a result. It falls into the trap of being just edgy enough to seem interesting, but not enough to make any meaningful statements. I get that the characters are intentionally one dimensional, but then they are given a complex problem like mental illness to deal with, it just doesn't feel real. I could never get invested in the characters, which made the big moments kinda lose their impact.
