I was hoping someone would make this thread. Also, this marks the first thread I've posted in in several months, so woo go me.
I finally got a PC in the house that can run games which were released more recently than 2003, so I can throw in my 2 cents.
Transistor - Considering how much I adored Bastion, I was pretty miffed when I found out my laptop couldn't run it because I was dying to see Supergiant's next foray. I shall disclaim this now: I think Bastion is an overall tighter experience, but Transistor is still an absolutely gorgeous 6 hour ride. The music is as on point as Bastion's was, visuals were striking and breathtaking and the general gameplay (salute) is an interesting blend of real time and turn-based combat. Bastion may have been more memorable, but Transistor is still leagues above a lot of other indies out there. The ending in particular is one that'll stick with me for a long time.
The Witcher 2: Assassins of Kings - So yeah, the new computer might be strong, but even the mere mention of TW3 makes it cry in the corner. So instead, I got round to playing its predecessor (which I got for free during a GOG sale woo) and was enraptured from the get go. Even being 4 years old, it looks amazing. As of time of writing, I've only completed the Roche path, though I'm working on Iorveth's. Based on that development alone, I enjoyed the story immensely. I liked how choices you make actually changed the world in some way, and I loved how certain quests, both main and side, had multiple ways of concluding them. I actually quite enjoyed the preparation for battle aspect of the game through making bombs and potions and whatnot, even though towards the end it became less and less necessary. Despite the cliffhanger ending, I felt it concluded satisfyingly, and definitely sparked my interest for the sequel.
Shadowrun: Dragonfall - Possibly the most surprising game I've played in a long time. I went in expecting isometric gameplay reminiscent of Baldur's Gate or PLanescape: Torment and a decent conspiracy plot tying all the various heists together. What I actually got was a tighter version of the recent XCOM, which I loved, and some of the best writing in a game I've ever seen, close to the level of the aforementioned Planescape. I played a Troll Martial Adept and punched my way to victory, though I always tried to defuse situations by talking, and it was just so satisfying. The narrative itself borrows the classic cyberpunk tropes and refines them to make a story whose notes seem familiar, but have their own special spins on the formula. I'm surprised to say that I unabashedly love the game to bits.
