I've been really (un)lucky these past few months, picking out games that were really addictive - just as I'd been unable to stop playing Alien: Isolation and Dying Light (though I still haven't finished the latter; the game really got me hooked in the beginning and I regularly went to sleep at 2 A.M., but just as I got to Old Town it kinda lost the grip on me a bit) I spent a lot of time already with Assassin's Creed: Origins, Bioshock (the first one) and I finally got into Fallout 3.
ACO: It's really much better than I expected, especially since the very first one was a bit of a bore. I love the Egyptian setting, the protagonist Bayek, the gameplay, the graphics... everything, really. It reminds me of the MCU movies - nothing really groundbreaking, but a very well-done craft that's worth every cent you invest into it. I guess you might say this is as "mainstream" as you can get, but I don't really mind - it's a wonderful gaming experience.
Bioshock: A bit late to it, I admit, but I'm enjoying it nonetheless. I am already in the final third of the game (so I've already experienced most of the twists) and it's really good, especially since the game also contains a philosophical/political discourse as well, it's very visually appealing and the storyline's quite cool (though despite me avoiding all spoilers I could still smell the main one twenty miles away, but the execution was still very cool). MAYBE, just maybe the game might be a bit too bleak, even for the point it's trying to get across - and remember, I'm a fan of Peckinpah, but still, those movies are about two hours, but fifteen in this world are much worse, innit?
Fallout 3 - like I said, at first I was a bit underwhelmed, especially as I'm playing The Outer Worlds concurrently and that one is definitely more colourful and interesting - at first. But I finally got into it and I just love it already (I'm Lvl 4 and so far mostly just done tasks for Moira and disarmed the nuke, but it's enough to get me hooked). Considering the fact I only played 2 (I believe it was the second one, but I'm not 100% sure) and I don't really remember it all that much, I'm probably not gonna complain neither about this one, Vegas or 4 (I know that many are divided, especially about the 4, but that's for the hardcores, I'd say. But we'll see). But then again, I always loved the game in theory (all that retro stuff, however ironic it may be meant, post-apocalyptic survival etc), so I guess it was mostly just getting used to the game proper.
Like I mentioned, I'm also playing The Outer Worlds and it's a good one - I haven't progressed much so far, but it's very enjoyable, has a load of interesting characters, some cool choices, it's very colourful (bordering on kitschy, but I don't mind) and the humour is definitely more subtle and actually funny than I feared from watching the trailer.
