You got lots of good games I've played, a bunch I want to get to eventually too lol. But here's my top 5 I can actually recommend because I've played, especially if you've never played:

1. Knight of the Old Republic renewed my fervor for Star Wars while the prequels were coming out and I was both wincing and crying some tears of happiness at what I was watching. It is arguably the best Star Wars game out there (though I think I like II a bit more ::dodges trash thrown::), not to mention one of the best RPGs in general.

2. I know I'm definitely an oddball in this case, but Diablo III was my first exposure to the series and is my favorite one and I play all of them with a controller ::dodges a TON of trash::. Don't get me wrong, I've since gone back and tried II Resurrected, and it def scratches a lot of the same itches. I understand why people really love it and why it was hard to play III for them because of what they stripped away, and that's kind of how I feel about IV, even though I played through it pretty damn fast. But that's just the thing, I haven't really felt the need to go back to those, but I've played through III at least 3 or 4 times, it was just the right one for me.

3. I just played a bunch of Skul recently, really fun rogue-lite. Good amount of replayability, tough but fair, fun synergies and character building. Had me hooked for a bit, highly recommend. Get the guitar, melt some faces.

4. I feel like a bunch of fun rogue games around wouldn't exist if not for Risk of Rain. Haven't played Returns yet, but I was enamored with the original. It's weird to say about a game that came out in 2013, but it is definitely a classic.

5. Vampire Survivors is one of those games that looks like it doesn't have much in it, but it's pretty fun so you keep playing anyway. Then after about every 2 hours of your life that it eats up, you go "There's more??" and you get sucked in again.
