GTA V, Dark Souls III or Witcher 3?

Witcher 3 wins hands-down. I wouldn't compare any of those games to W3.

Only Witcher 3 the best game. Also I recommand books, awesome.

I guess the poll votes are a quite accurate representation of the general consensus, although we all have different tastes, as well as a wide variety of PCs.
I took a look at your library, and I see you have played a lot of hours in RPG and strategy games, including Dark Souls 1 and 2, as well as The Witcher 1 and 2, but nothing even remotely comparable to GTA (at least on Steam).

But both dark Souls 3 and The Witcher 3 require pretty powerful hardware, while GTA V is a good port which can run on low end hardware.
Judge your decision on the above info, as well as your own personal taste:
would you rather complete the Dark Souls series first, or The Witcher? Or try something completely different?

Make sure to get the GOTY version if you get The Witcher 3, the expansions add a lot of content. Mind that you can get a Steam copy only on the Steam Store, as every other place sells GOG keys. It's DRM-free anyway, though.

Of course, wait for the imminent Winter sale to save a bit of money, unless you choose GTA V, which is unlikely to get a better discount so soon.
Similarly to The Witcher 3, you can get a Steam copy only from the Steam store, as every other place sells Rockstar Social Club keys (you need an account and their launcher anyway to play).

witcher 3 for world and story, followed by dark souls 3 for gameplay and atmosphere, followed by gta v for... hookers, i guess?

After playing 10 hours of Witcher 3

Also recently Witcher 3's Blood and Wine DLC won Best RPG in the 2016 Game Awards, defeating a few AAA games in the genre.

Maybe GTA V for the MP feature.

I am a huge fan of the GTA since the beginning of the series and GTA V is great too, BUT i would advise you to go with The Witcher 3 honestly, I am really not into games like that that have magic and stuff like that but The Witcher 3 is one of the best games I have ever played, even story DLCs are great too. Grab The Witcher 3 - Game Of The Year Edition and you wont regret it :D

Get GTA V since it's on sale, you can get the rest when they are on sale as well.

Also, finish Dark Souls 1 and 2 if your Steam hours are accurate.

Witcher 3, it's DLC got the RPG of the year. What else could you ask for?

GTA V has a good and fun storyline but the multiplayer isnt that good if you're not playing with friends.
It has lot of loading and waiting time may be long sometimes.Players sucked and you will waste lot of time because of that.

I dont own Dark soul or witcher so i cant really talk about it.

Witcher 3 > GTA 5 > DS 3. All worthy anyway, DS 3 is really punishing and the worst in the series though.

GTA will always hold a special place in my heart. Since its on sale, I would just get that for now. I have only played the SP so far but really enjoyed it. Thought the story was pretty great. Entire plot is connected to the prologue. Thought that was pretty interesting. Own it on Rockstar website.

All good games but I like the Witcher 3 the most!

It's not even a contest. Witcher 3 100% It's literally the best RPG ever made.

witcher 3 without an ounce of doubt

Save your money. Buy those underrated $0.99 indies.

With your name being Rockstar going to assume you like Rockstar titles, GTAV is a brilliant game, as they all are. GTA V wins based of what info I have.

All of them

Witcher 3 expansion pack.(or gta 5)

Witcher 3 by far ...

sound tracks and big bosses are awesome for DS3...

Dark Souls 3
