You should have played Black Mesa instead of Half-Life 1 these days. It’s not a 1:1 remake but quite close and of course much more modern, and just awesome. Xen in particular is much better in BM than it is in the original, so it even fixes HL1’s weakest part. The rest is kind of similarly awesome. Maybe you should play it right now to see the difference.

(Black Mesa is a successful fan project remake of the whole Half-Life 1, and they even expanded on some things (especially Xen). It’s based on an updated Source engine and has at least the graphical fidelity of recent Half-Life 2 builds, if not more).

• Cyberpunk 2077 (very good since 2.x and with Phantom Liberty expansion). Since I have similar hardware to you, you can play it with Raytracing enabled and have at least above 30 fps which should be enough for most playstyles except maybe fast melee-based combat. The game’s lighting effects look absolutely gorgeous with Raytracing.

• Witcher 3 (keep at it. It’s amazing. It can feel clunky at the beginning due to its weird combat mechanics but you get used to it. Also you can switch it up by integrating signs (magic) into your swordfighting. Which is what I recommend doing. I think it’s more varied). Also, the game gets better as you go. The base game is great, but the DLCs are even better, especially Blood & Wine has kind of a legendary status among all DLCs, you rarely get such value inside a DLC, except Phantom Liberty which has a similar scope and quality to it.

• Baldur’s Gate 3 is probably the best game of the last decade or so so highly recommended. It’s not open world, but it’s still huge and is at the same time very densely packed with stuff, so you need a lot of time when you want to explore and loot everything. The game feels huge that way. Especially compared to open world games, it’s like the opposite - open world games have a vast area but almost nothing in-between major points, which means the world can feel empty in a lot of open-world games. Baldur’s Gate 3 has something around every corner and never feels empty (unless you’ve cleared a whole area already).

• Red Dead Redemption 2 - a lot of people like it, so far it didn’t feel right to me (so slow) but I can still see how it’s a good game and if you like chilling with a game it might be just your thing

• Elden Ring is amazing but has very tough combat/action of course. Still, it really feels great as an open-world game. It completely throws the “Ubisoft formula” out of the window, which most open-world games follow, and that’s precisely why it’s so good. I’ve rarely had more feeling of true exploration and accomplishment within an open world game. Still, combat is very challenging, so if you prefer games to be on the easy side, then it’s not right for you. But if you don’t mind a challenge (a challenge you can also often delay for later when you’re stronger) then it’s a must-play. If you don’t know, as most or all games from From Software, these games don’t offer different difficulty settings so there is only one difficulty which is the same for every player (and it’s tough). These games are also very fair and reward accurate playing - it’s possible to not get hit at all by anything, for example, if you’re really good. So they never feel unfair and when you die (which you do a lot) you’ll always know why you died and have an idea how you could do it better. Besides the difficulty, what can also feel oppressive in those games is the fact that all enemies (except bosses) respawn whenever you rest. But Elden Ring kind of mitigates that because you can skip a lot of areas and come back when you’re better prepared (i.e. gained more levels/attributes or better gear). Then, past challenges can start feeling easy. And skipping weak enemies is kind of the normal thing.

• STALKER 2 (may still need a couple more patches but it’s playable and has a great overall atmosphere and visual design. They fixed the worst post-launch problems I think). Very strong in atmosphere and immersion.
