I'm an old nerd with opinions raaaaaaaaaaage oh, this isn't so bad. It wouldn't be my list, maybe only 2 or three games on it but it's well reasoned and like all criticism, subjective.
Minecraft (2009) -Respects players ability to work things out. Near limitless ability to modify the world itself.
Legend of Zelda: Breath of the Wild -Dosn't bite for everyone, but it's learned the lessons of Dark Souls and Witcher 3. Exploration is as open ended, brutal and off-rails awesome at the '86 original. A game that makes empty space work for it.
Dark Souls (2011) - Respects players ability to work things out. Pity abou the MP hacks. I can see why it's some people's GOAT but it aint mine. Maybe a better PC port would have made things different.
Half-Life 2 (2004) - I'm not sure if I ever want to play it again, but I've been through half a dozen times. Very good important game, not sure how much it did other than the face and maybe physics shit that I would say pushed the genre forward, though lenghth, quality and set pieces are to be commended.
The Witcher 3: Wild Hunt (2015) - Not my jam but I can see why this is the GOAT for some. Combat is still ass, eastern european both sides cynicism just isn't for me and is everything I hate about modern nerd culture.
Grand Theft Auto V (2013) - It sold a lot! Hard for me to put in top 10 though. RDR2 outdoes it for narrative for sure.
Halo: Combat Evolved (2001) - I love this fucking game. Probably the one I've finished the most, on every difficulty setting it's a different kind of fun. Split screen co-op, enemy AI that is fun to fight. Fucking hype. Makes me want to watch Starship troopers and join the space fascist navy!
Portal 2 (2011) - Phenomenal game. I guess it's better than the first, I recommend both to everyone to be played in order. Probably deserves to be here though I doubt I'll ever go back. It's not as dynamic as some of the murder sims here so it's always going to play sam-ish and the jokes are all done, like my beloved lucasarts adventures.
BioShock (2007) - Get it off! A flawed but brilliant game. Playing the remaster reminded me that it's a shadow of the promise of Thief/Ultime Underworld/System shock. But then what the fuck isn't. Newest Prey is a much better one of these.
Bloodborne (2015) - Meh. Faster Darksouls. I can see why people love it, and I'm a big believer in the gift of consolitist inspired "no-quick-save you fucking have to nail this section!" gameplay but I play to relax most the time. Still big respect. I got lost in some sewer and died after some amazing exploration and nailbiting combat but lost so much progress I never want to experience it again. (Unless it gets Sekiro quality PC remake like DS needs)
Ok here is where you fucked up motherfuckers, top ten must haves this century according to all I can think of right now but I'll probably disagree with in the morning or forgot some 400 hours masterpiece but to be the greatest it needs to compare favorably to everything that came after, or at least that's how movies/books/creative peoples/scientists work:
1. Kerbal Space Program
2. Spelunky
3. Into the Breach
4. Factorio
5. Halo 3
6. Outer Wilds
7. BATTLETECH
8. Morrowind
9. Crusader Kings 2
10. Minecraft
Games that should be in top 10 but didn't quite nail it/too much room for improvement/in because my daughter loves playing them as well/idiots couldn't get matchmaking right in AU (PUBG)
Samurai Gunn, PUBG, all the civs, all the Behemoth games since Castle Crashers, mark of the Ninja, Elite, DCS, Chivalry, Sekiro:Shadows Die Twice, Destiny(s), heaps more probably!
