Initial scrolling of the Steam Summer Sale seems pretty lackluster, but digging through the comments sections in other threads, a few gems have stood out, and it doesn't appear we have a thread dedicated to this yet, so post what you think are the best deals here!
Not mandatory ofc, but it'd be helpful if...
One game per top level post, so comments stemming from it are focused on on just it.
Include a short blurb about the game - if it's one you've played before, what did you like about it? If you're diving in blind, what grabbed your attention?
If you've somehow managed to avoid Witcher until now, it's a dark medieval fantasy, 3rd person, open world RPG based on Norse Slavic mythology. Lots of political intrigue, choices that actually impact outcomes in game. Fantastic voice acting, story, soundtrack, and combat/gameplay mechanics. This is one of the best games on the market - if you don't already have it, now's the time! There are also two DLCs that are each the size and scope of an entire standalone game - don't miss those!
Once you get a hold on dodging/parrying/etc, you'll feel like a damn ninja, especially on harder difficulties; but leading up to that, yeah combat is... OK. Also don't miss out of experimenting with different builds - one of my favorites optimized using bombs, which later into it makes you a walking B-52 - fun build if you enjoy clearing trash via a wave of pure chaos, then mopping up the stronger guys by way of the sword.
And yeah, the whole package is what counts here: Witcher 3 is a fantastic all around game. It isn't without it's imperfections, but they are barely noticeable amidst the tsunami of ridiculously high quality you'll be hit with from all the other features.
Witcher 2's controls are a bit janky, but it's a solid game in and of itself for the story alone; if you can stomach some pretty bad mechanics to enjoy an otherwise decent product, I'd say start at #2.
Witcher 1 is... so bad it's kinda comical. I'd just pull up a story summary of Witcher 1 on youtube and call it a day. If you're a masochist, go ahead and give the actual game a whirl; but I'd recommend modding the snot out of it to at least make your character OP as fuck, allowing you to mostly skip the god-awful combat. But even then, the only selling point is the story, which again you can just pull up on YouTube.
That said, you can dive into 3 with zero knowledge of the previous two and be just fine. There are things that will go over your head, but nothing significant.
It helps if you know the lore, because at the beginning there is a scene where someone asks you about decisions you made in the first two parts. But I didn't know anything and just guessed.
But after that you don't really need to know what happens before
