1. Uncharted 4: A Thief's End
Absolutely loved it I must say, it's an absolute masterpiece, the combat is better and more inventive, the graphics and attention to detail staggering, the story is the best of any Uncharted game and the character development of all of the cast is greater in this one game than U1-3 combined.
This is the only game in the series that has lived up to the hype, and only one I love.
2. Dark Souls 3
The best game in the entire Souls-Borne series for me. I didn't get into the series until Dark Souls 2 (which I loved), Bloodborne surprisingly left me cold though, it just didn't resonate with me like it did others for some reason.
Dark Souls 3 was a return to form, it had the varied environs from DS2 but coupled with the interconnected level-design of Bloodborne and the original Dark Souls, it can be considered a 'greatest hits' to some, but I think it is the most polished and well-thought out of all the games in the series and truly an incredible game.
Incredible characters you actually care about and are a ton of fun to play, all unique in their own ways and so damn fun. It's just so deep, so well balanced, so fun to play and Blizzard keep adding more and more content and speaking more with the community to make it better, truly one of the best multiplayer shooters of all time.
4. Titanfall 2
It's an absolutely phenomenal, flawless campaign and one of the very best I've ever played, it's honestly flawlessly executed.
Each level brings something genuinely new and different to the table, it never rests on its laurels and apes games like Half-Life 2 and Portal at the beginning and then the bombast and sheer spectacle of Call of Duty at the end.
It looks absolutely phenomenal and runs like a dream as well, sumptuously exotic environs in every level, futuristic factory's that somehow manage to remain interesting and inviting where so many similar locales in other games end up dull. It's truly amazing how grounded Respawn have made it feel as well, the gunplay is absolutely sublime and up there with Destiny for sheer satisfaction when killing enemies, I also liked that it was so easy to headshot them, they weren't bullet sponges and were all the better for it, the AI wasn't incredible on the Regular difficulty but then it never needed to be.
The biggest triumph though is that for such a Sci-Fi world the writers managed to think of a story that is incredible personable and low-key. At the start you're essentially a guy stuck on a hostile planet with 1 companion to keep him motivated to keep on moving through an alien world, with the aim to signal to the other Militia members that you're there and transmit them key information. It takes some real balls to keep the story that human, and reel-in the more futuristic sci-fi elements for something that still feels real and present. It's almost the exact opposite of CoD:IW's campaign, with it constantly reminding you how futuristic and Sci-Fi it can be, Respawn showed real restraint not going down that route and telling the story of one guy and his robot.
The story isn't perfect though with Jack Cooper being possibly the most generic character ever, but he's a Blank slate, never really gets in the way, and let's BT take centre stage as the real star, adding some much needed personality to the proceedings.
Some will bemoan the short length of it, but it's a perfect length for me and never outstays its welcome, always feels fresh and you're always on the move, no time to ponder and always puts you at the centre of the action. I really would rate it up there with Half-Life 2 and Portal, it's a truly remarkable Campaign that'll hopefully be remembered as a Classic for years to come.
Cannot recommend it enough.
5. Forza Horizon 3
The range of environs have definitely improved, you're right, so varied now, wine regions, sand dunes, cityscapes, rainforests, it's all there! They've cherry picked the best Oz has to offer and chucked it in the game.
I think its the best racing game since DiRT 3, it's probably better than that, one of the best racing games of all time for sure.
