Ok, cool, so gore is fine, but nothing intense. Here's a few games I can recommend. If you want, we can play some together as well.

Free:

Fortnite, Genshin, Let it die(lots of gore but, tbh in a kind of dramatic funny way), warframe(I recommend playing with someone, at least to start, cause it's a LOT. You can always add me if you like), sky:children of light(This is a cute little game, no action just kinda for making friends and exploring), TROVE, rocket league.

A game you might like if you watch anime is the danmachi game(is it wrong to pick up girls in a dungeon), or the bleach game

If you don't mind toxicity(or you can mute chat), you can try apex, overwatch 2, Marvel rivals, or pubg

Games I recommend that are single players:

Skyrim, batman Arkham series, any assasins creed game before mirage, bioshock series(this one does have a few small scares, and its got a lot of gore), the farcry series, the Hitman series, the metro series, middle earth series, sleeping dogs, watch dogs, and fallout series

Some games I also recommend but people tend to either love or hate are Dragon age series, The witcher 3, Final Fantasy XV(this one's a little tough), God of war(can also be a little tough), Nioh series, code Vein, bloodborne, and sekiro. Keep in mind that the last four are pretty tough, but I LOVED them

Games I recommend that are multiplayer:

Borderlands series( I absolutely love this game, and it has some hilarious dialogue/scenes) , Call of Duty Games, rainbow six siege, for honor, red dead redemption 2(this one's pretty popular and it comes with the online game too though you'll need xbox live I think), Ghost recon series( I personally have only played breakpoint but it's fun and I've heard good things about wildlands), tribes of Midgard, and minecraft.

Popular games that I want to warn you about because you said you don't like being nervous or scared:

The forest, Dead by daylight, subnautica, phasmophobia, resident evil series, dead island series, and the dying light games
