Easily Halo 3.

Halo CE has very poor level design by today's standard. Incredibly repetitive copy paste stuff and backtracking for hours.
Halo 2 improved a little in that regard on most levels but overall had more levels with poor design compared to CE.
Halo 3's only flaw is the level Cortana which is easily the worst level in the game but I'd still much rather play this than the bad levels of the other Halo games. Other than that huge step up from the other Halo games. Tons of new vehicles and weapons and an exciting story.
Halo 3 ODST was alright. Wouldn't put it anywhere close to the main series though.
Halo Reach was pretty good as well.
Halo 4 is okay but still haven't finished it. Great graphics for a 360 game and gameplay is as good as ever. Story-wise I didn't care much.
Halo 5 is similar to Halo 4 in that regard but I had more fun playing it.h Sadly a little short.

Not going to rate Halo Wars and its sequel as I don't think comparing RTS to FPS makes much sense.

Halo 3 > Halo Reach > Halo 5 > Halo CE > Halo 4 > Halo 2 > Halo 3 ODST

Decided to make an update (last one was in March 2019 so pretty much a year) even though the vast majority of newer games doesn't support time tracking anymore. If possible, I'm going to use in-game times for newer games. Expanded the list to 25 since I hate kicking games out lol.

AC Odyssey took #4 and I'm not done with it just yet. Need to do the whole Atlantis DLC and 2/3 of the Legacy of the First Blade DLC. According to TA that should take another 22-29 hours. It will claim the top spot soon.

The next one is actually my mistake. I just noticed that both Minecraft (Bedrock) and Minecraft X1 Edition have their own time trackers. I never considered them individually but I don't see why I shouldn't combine them for this purpose. Would've made the list a lot sooner but can't change that anymore. Nevertheless I play it every time there are new achievements released which is quite often. It's the new #13 with a good chance to rise a little in the future.

Kingdom Hearts III was my game to play in November. The result is #18. Not sure if I'm getting the Re Mind DLC as it doesn't seem that exciting and is really expensive. Will probably drop from here on.

Shadow of the Tomb Raider made it from #24 in March to #19 thanks to its short but numerous DLCs.

Jurassic World Evolution dominated the last days of 2019. There's only an in-game tracker which puts my last save at 30.90 hours. However, I'm pretty sure I reloaded an earlier save to get an achievement here and there so the time is probably closer to 35 hours. Unfortunately it's impossible to tell at this point. At the very least, it's #21 on the list.

Forza Motorsport 6 saw a rise to #22 due to me playing the Porsche and Nascar DLC

Played quite a few games in the 20-25 hours region since the last update. The Outer Worlds missed the top 25 but could make it once the DLC is out. The same is true for Rage 2 (for which the DLC is already released). Another recent game that didn't make the list is Crash Bandicoot N. Sane Trilogy. It fell around 3 hours short. Trials Rising missed the top 25 by 5 hours.

Looking at the future, Red Dead Redemption 2 will eventually make the list. Currently 9 hours in but haven't played it in a while. Other than that there is pretty much nothing in sight that would come close. But who knows, maybe something will drop on Game Pass.

3 > R > CE > 2 > 4 > 5

By that last part I guess that he means both 1st party studio/s and 3rd party exclusives, they will need to secure a good portion of Japanese exclusives for Gamepass to succeed over there.

It doesn’t even need to be AAA level, games the size and scope of Astral Chain, Atlier Ryzer, Daemon X Machina, No More Heroes 3 and Deadly Premonition 2 would be enough, all those titles are between AA-AAA and would not be that expensive to fund.

Had I played A Plague Tale: Innocence in 2019, it would've been my GOTY. 

A wonderful, immersive game with well-written story and characters. I liked the variety and build up of gameplay mechanics and skills. It starts as a distressing survival/stealth game and then builds up to much more than that. 

There are other games that use the same light and dark mechanics for puzzles and combat, but A Plague Tale does it with such twist it's very clever. You really don't want to step out of light.. 

There are negatives though. Enemies are dumb as fuck.. a guard sees you take out 3 of his buddies, but after looking around for a minute he says "hear that? Nothing but silence. Time to stop searching". Then he starts staring at an alley. 

They could've done a bit more with Amicia's and Hugo's complex relationship at the beginning. They hardly knew each other and Amicia was a bit jealous of Hugo. 

Still I think this game is worthyof a full 10/10 score. Enjoyed every second of it. A good list of achievements too that don't require multiple playthroughs.

One more thing.. I kept expecting the big twist Angelus mentioned, but it never came heh. Left me scratching my head a bit.

Edit. Forgot to mention visuals, facical animations,  audio and voice-acting are excellent.

Started it yesterday and played through the first episode.

Just wow. Incredibly immersive world, characters I felt immediately attached to and astounding visuals (had to turn off chromatic aberration as the effect was way too strong. Looks even better without it).

And that's just from ~40min of gameplay.

I mean, it's not so much a big twist, as it is a weird ass fucking turn. But hey, if you were expecting the game to end up where it ended up....

The Division 2 is pretty cheap but might hit Game Pass soon.
Nevertheless, might be better to just buy it so you don't have to force yourself to play it within the next 12 months before it gets removed.
