Star Wars Rebellion (or Star Wars Supremacy in Europe) had a GameRankings score of 50 but I had a blast with it. I must have had 200 hours in it over the years. As a 4X game, it's definitely below average, and there's zero challenge once you figure a few things out.

Where it succeded was by being a bit of a sandbox with a fun license. The soundtrack is phenomenal, there are recognizable names everywhere, and the moment when you get to go toe-to-toe with the Empire after scrapping together a fleet big enough is great. Problem is, it had a rough interface, obtuse mechanics, glacial pacing, and that epic fleet battle looked so bad it probably would have been better off being icons on a star field.

I also think Lightning Returns: Final Fantasy XIII (72) and Rune Factory 4 (79) were underrated, especially the latter. I think to this day, RF4 is the best game in its genre (and that includes Stardew Valley).

Silent Hill Origin and Downpour.

I looked at the metacritic page and it was tbd, like no outlets even rated it... And it's a console and pc game with a physical release!

Anyway it's Bullet Girls Phantasia, an even lower budget EDF like game, but in a Isekai setting and the girls have their clothes ripped when they suffer enough damage, beat it multiple times.

Starfield, which I don't get the sheer magnitude of rancor it gets... It's not perfect, but it's still a good game, and none of its issues are "unfixable", no matter how much its haters want to believe they are

Genuinely had a lot of fun with it and looking forward to content updates, as well as yes bug fixes and gameplay improvements (I did say it's not perfect, but none of Bethesda's games were really better at launch and most of them got slammed initially too)

King's Bounty 2. It's not an amazingly well made game, and it lost a lot of the fun goofiness of the other games, but I do love the combat and think the story was underrated.
